Abstract: Provided is an in-plane response-type liquid-crystal display device having a sufficiently high contrast ratio enough to display high-quality images. The device is free from the problem of light leak to be caused by spacers, and is free from the problem of rough surface appearances. In the device, the surface of each spacer is coated with a thermoplastic polymer prepared through graft polymerization of a molecular compound having a vinyl group or a polymerization initiator, with one or more polymerizable monomers. The functional groups existing in the surface of each spacer are bonded to the alignment layers adjacent to the spacers via van der Waals bonding or hydrogen bonding, whereby the spacers are fixed onto the orientation film on at least one of the electrode substrate and the color filter substrate constituting the device. The bonds are extremely small, and the region around the spacers through which light will leak is much reduced.

Abstract: The widths of those portions of a semiconductor layer 5 and a drain line 6a overlapping with it which cross an edge line of a gate electrode 2 are made smaller than the channel width of a thin-film transistor. With this measure, the overlap area of the gate electrode 2 and a drain electrode 6 is reduced. As a result, a variation of the above overlap area due to alignment errors in a photolithography apparatus used in patterning the gate lines 2, the drain electrodes 6, and source electrodes 7 can be reduced and the frequency of occurrence of display defects can be decreased.

Abstract: A reflection type liquid crystal display is formed by an interlayer insulating film having appropriate unevenness of an inseparable pattern in a picture element region and having a contact hole of a separable pattern on a drain electrode of a TFT is formed by plainly applying a photosensitive insulating resin so that it may dissolve difference in level caused by a gate electrode wiring, source electrode wiring, and the TFT, and conducting exposure and development while changing exposure amount. The exposure of the insulating resin is conducted through divisional exposure in which the inseparable pattern and the separable pattern are arranged on different masks, and the inseparable pattern is exposed by a predetermined exposure amount of 20 to 80% of an exposure amount for the separable pattern.

Abstract: An integrated circuit including a liquid crystal display has a multi-port data output section from which output signals are arranged with respect to a data input signal. Points of changing the signals with respect to a time base are set with time delays that lag behind one another during one period of a reference internal clock signal to reduce the number of simultaneous changes of output signals. The electromagnetic field noise is reduced by a LCD driver when display data are transferred from a LCD timing controller to a source drive IC. The driver includes TFT drive and display timing control circuits that transfer red, green and blue color display data formed of plural bits to the TFT drive circuit for each bit unit formed of plural bits, optionally selected from each of the color display data. A delay unit in the display timing control circuit delays the transfer timing among bit units. A dedicated IC supplies image data to a source driver IC that drives a display section.

Abstract: A prism member is interposed between an LED board and a light incidence surface of a light guide plate. The prism member includes a prism sheet consisting of minute prisms that are arranged along the LED board and that have a function of refracting light that is emitted from each LED and thereby inputting, to the light incidence surface, refracted light that is scattered to both sides in the longitudinal direction of the light incidence surface. As a result, chrominance or luminance unevenness can be prevented even if the distance between the LED board and the light incidence surface is short.
