    摘要: The display device of the invention comprises a plurality of scanning lines (Wscan and Escan) which are selected successively, a plurality of data lines (Data) to which the writing electric current (Idata) in accordance with brightness information is supplied according to the scanning line selection, and a plurality of pixels (PX) arranged at intersecting points between the scanning lines and the data lines. Each of the pixels comprises a light emitting element (OLED), a driving transistor (TFT4), a capacitor (C) connected to the gate (Nd) of the driving transistor for accumulating writing data, a first transistor (TFT1) which is turned on during writing period in which the scanning lines are scanned and which connects the data lines and the drain of the driving transistor, and a second transistor (TFT2) which is turned on during the writing period and which short-circuits the gate and drain of the driving transistor. With such a structure, the light emitting element can be driven with a driving electric current equivalent to the writing electric current, irrespective of variations in characteristics of the transistors,

    摘要: The invention relates to a backlight unit for liquid crystal displays, etc.; and its object is to provide a backlight unit not involving the problem that the emitted light leaks out of the optical waveguide, even when the space around the cold-cathode tubes in the light source unit for it is filled with a liquid of which the refractive index is nearly the same as that of the glass material that forms the outer wall of the cold-cathode tubes. The backlight unit comprises a housing 6 which houses cold-cathode tubes 2, 4 therein and of which the inner surface is coated with a light reflector 10; a transparent liquid filled in the housing 6; and an optical waveguide 1 made of a transparent substance and having a light-emitting surface S. The reflective surface of the light reflector 10 has a cross-section profile of X-T-U-V-W-Y, on which the light emitted by the cold-cathode tubes 2,4 is reflected, and the thus-reflected light is led to the light-emitting surface S of the optical waveguide 1 at an incident angle not smaller than the critical angle to the surface S.

    摘要: A liquid crystal display device includes: a liquid crystal spatial modulating element holding a liquid crystal layer between a pair of parallel substrates, wherein transmission of light incident upon the liquid crystal layer along an incidence direction tilted to a predetermined direction from a normal to the substrates takes a local minimum as a voltage applied to the liquid crystal layer is changed, and the voltage at the local minimum changes as the incidence direction is changed; an illumination optical system for supplying illumination light generally over a whole surface of the liquid crystal spatial modulating element along incidence direction or directions tilted to the predetermined direction; and a driver circuit capable of applying a voltage across the liquid crystal layer, the voltage being generally equal to a voltage which provides the local minimum of the transmission with respect to the illumination light. The liquid crystal display device has uniform display characteristics over a display screen.
