摘要:
The active matrix type liquid crystal display device has a plurality of liquid crystal elements. Each liquid crystal element has a transistor section, a transistor side conductive light shielding film electrically connected to the transistor section, and a liquid crystal element having an opposing electrode coupled to the transistor section. There are a first potential terminal connected to the opposing electrode and a second potential terminal connected to the transistor side conductive light shielding film with a potential applied by the first potential terminal being independent from a potential applied by the second potential terminal. With this arrangement, the lateral field components around the pixel portion, which become a cause for the reverse tilt of the liquid crystal, are relatively reduced with respect to the vertical field components, thus reducing the disclination and providing excellent display characteristics without residual images.

An active-matrix liquid crystal display device applies a voltage modulated with a high-frequency AC voltage to a common electrode disposed on a substrate which confronts a substrate having a plurality of thin-film transistors as switching elements for pixel electrodes. The modulated voltage applied to the common electrode is effective to reduce the phenomenon of a residual image retained for a long period of time; thereby improving the quality of displayed images.

An active matrix LCD device has a plurality of pixel elements arranged in a matrix for display. The electric field generated between the pixel electrode and the common electrode is diagonal to the normal of the surface of the electrodes. The diagonal electric field is achieved by a slit formed in the TFT panel between the pixel electrodes and the common electrode, or by protrusions formed on the surfaces of the electrodes.

A dedicated control signal electrode is provided between pixel electrodes, and a strong electric field is generated between the control signal electrode and the common electrode to quickly and securely make an initial transition from liquid crystal molecules in a splay alignment state to the same in a bend alignment state. In addition, generating a strong electric field between the control signal electrode and the common electrode even during operation for displaying an image makes liquid crystal molecules stably stay in a bend alignment state. In this case the scan signal electrode, the video signal electrode and the common electrode, which are required for displaying an image, are not used to make a transition from liquid crystal molecules in a splay alignment state to the same in a bend alignment state and make the same stay in a bend alignment state.

An LCD device that is able to remove the luminance unevenness on the display area while preventing the short-circuit and open-circuit is provided. The LCD device includes a liquid-crystal panel having first and second substrates and liquid crystal filled in a space formed between the first and second substrates. Pixel electrodes are formed on the first substrate and are arranged in a matrix array in a display area of the panel. Driving lines are formed on the first substrate in the display area and are electrically connected to the respective pixel electrodes. Terminal areas are formed on the first substrate outside the display area. Driver ICs are mounted on the first substrate outside the display area and are electrically connected to the corresponding terminal areas. Connection lines are formed on the first substrate outside the display area and are electrically connected to the respective driving lines and the corresponding terminal areas. The resistance difference of any adjacent two ones of the connection lines is lower than a threshold resistance value at which a man is able to recognize the luminance unevenness on the display area.

Light shield areas 20 are formed between terminal groups 15 in a side near outgoing line groups in a display portion of a liquid crystal panel. This configuration is useful for reducing uneven brightness in a horizontal direction in the side near the outgoing lines in the display portion so as to improve the display quality.

An OCB type liquid crystal display having first and second substrates opposed to each other via a liquid crystal layer such that rubbing directions of the first and second substrates become parallel to each other, a plurality of pixel electrodes which correspond to respective pixels, and a common electrode formed on the second substrate which receives a reference voltage commonly to a plurality of the pixels. A first transition nucleus area is formed in the first substrate layer and has a plurality of continuous slant surfaces having a saw-tooth cross sectional profile, and a second transition nucleus area is formed in the second substrate and has a plurality of continuous slant surfaces having a saw-tooth cross sectional profile. The slant surfaces in the first and second transition nucleus areas oppose to each other and slope toward mutually opposite angular directions.

A lightweight metal spoiler is integrated with a tailgate of an automotive vehicle. The integrated tailgate spoiler is formed from the same material as the frame or rear portion of the tailgate body, preferably aluminum, in one arrangement and from different materials in another arrangement. First and second spoiler portions are joined together along overlapping, mating, abutting edges. The first and second portions of the tailgate are brazed together at an acute angle and the unitary spoiler is fused to the rear portion of the tailgate body.

[Problem] To provide a light-emitting device which does not undergo the deterioration in luminous efficiency associated with the long-term use.[Solution] A light-emitting device (1) comprises a light-emitting element (10) which can emit blue light and a phosphor (2) which is composed of a single kind of single crystal and can emit yellow light upon the irradiation with the light emitted from the light-emitting element (10) which serves as excitation light. Thus, it becomes possible to prevent the deterioration in luminous efficiency associated with the deterioration in a binder or the like compared with a light-emitting device which utilizes multiple kinds of granular phosphors, because any binder for binding phosphors to each other is not required in the light-emitting device (1).
