A pixel electrode connected to a signal line through a switching element and a common electrode connected to a common wiring are disposed, as alternating with each other, within each pixel region. Common potential lines are disposed on level below the signal line with an insulating film in between and also on both sides of the signal line when seen in plan view. A floating electrode is disposed on level above the signal line with a protective film in between, as overlapping the signal line and the common potential lines on both sides of the signal line.

A TV microcomputer makes a request to a wireless center microcomputer through a SS transmitting/receiving unit in a TV main unit and a SS transmitting/receiving unit in a wireless center, and the wireless center microcomputer sends a response for notifying reception of the request command to the TV microcomputer through the SS transmitting/receiving unit in the wireless center and the SS transmitting/receiving unit in the TV main unit. The TV microcomputer processes the received request for an auto scan, and transmits channel identification information for setting a channel, which includes skip information indicative of whether or not a station for the channel exists, to the TV microcomputer as a response for notifying completion of the process. The channel identification information is stored in the TV main unit. Further, when an up-down channel selection is performed, the channel identification information is referred to identify a selected channel, and the identified channel is transmitted to the wireless center as a direct channel selection command. This reduces a delay time involved in the exchange of commands.

A full-color lateral-electric-field LCD device has an organic transparent film having three different thicknesses for the pixels having RGB colors. The thicknesses dR, dG, dB of the organic transparent film and the representative wavelengths λR, λG and λB of the color filters satisfy the following relationship: dR:dG:dB≈λR:λG:λB. The different thicknesses provide different thicknesses for the LC layer, to improve the image quality of the LCD device in a slanted viewing direction.

An active matrix liquid crystal display panel by which a good display characteristic can be obtained without suffering from gradation reversal over a wide visibility angle range. A liquid crystal layer 4 is formed such that the thickness thereof varies in accordance with transmission wavelengths of color layers 6, 7 and 8 so that a very good display which does not exhibit any coloring in whichever direction it is viewed may be obtained.An active matrix substrate A includes a plurality of opposing electrodes 2, a plurality of pixel electrodes 3 parallel to the opposing electrodes 2, a thin film transistor, and an orientation film 23 all formed on a glass substrate 10. A color filter substrate C includes an orientation film 56 provided on one surface of another glass substrate 10 and an optical compensation layer 35 provided on the other surface of the glass substrate 10 and formed from a plastic film. The two substrates are disposed such that the orientation films thereof oppose each other, and polarization plates 34 and 5 are disposed on the outer sides of the two substrates, and a liquid crystal layer 4 having a positive refractive index anisotropy is provided between the orientation films 23. The optical compensation layer 35 has a negative one axial refractive index anisotropy and can cancel a retardation produced in the liquid crystal layer 4 thereby to suppress white floating of a black display portion.

An active matrix type liquid crystal display device in the lateral electric field system is disclosed, in which a high aperture factor is ensured even in a narrow pitch case, while also ensuring high contract and reduced vertical stroke is disclosed. In a liquid crystal display device, in which substantially bank-like third insulating film 208 is formed a video signal line 204 and covered by a common electrode 210, a light shield electrode 213 is formed underneath an extension of a common electrode 210 from an edge of a video signal line 204. With this arrangement, a liquid crystal display device is realized, which shields light from the sides of a step part as well as ensuring high aperture factor and high contrast.

An in-plane switching type liquid crystal display device includes (a) a first substrate on which a plurality of gate lines and a plurality of data lines are formed such that the gate lines are substantially perpendicular to the data lines, and on which at least one pixel electrode and at least one common electrode are alternately formed in each of pixels defined by the gate and data lines, (b) a second substrate facing the first substrate, and (c) a liquid crystal layer sandwiched between the first and second substrates, wherein when a voltage is applied across the pixel electrode and the common electrode, liquid crystal existing on extensions of the data lines are caused to rotate in a plane substantially in parallel with the first substrate. Both the pixel electrode and the common electrode have at least one bending point at which the pixel electrode and the common electrode bend, and are designed to bend such that both an intensity and a direction of a field generated by the voltage successively vary.

An active-matrix LCD device drives the LCD panel by using a dot reversible driving technique. The switching between two sets of input signals or two resolution modes is conducted by applying a DC voltage between the pixel electrode and the common electrode in each pixel before restart of the image display of a switched signal. The DC voltage has the same polarity among the pixels in the pixel array to thereby reduce the flicker after the restart of the image display.
