Problems solved by technology

[0010] However, to use such a liquid crystal, in order to make it from figure 1 To transfer the splay orientation 51 shown in (1) or (2) to the bend orientation shown in (3), it is necessary to continuously apply a high potential difference to the liquid crystal layer for a certain period of time or more. Applying such a voltage will put a burden on transistor devices and wiring, and the price will increase
That is to say, a technology that can easily and accurately perform such a transfer with a voltage, current, etc. that can be tolerated in devices, wiring, etc. that are widely used today has not yet been realized.
As a result, this type of liquid crystal has not yet reached the point where it can be used universally

Embodiment 1-1

[0078] Here, "(Example 1-1)" means "Example 1 of the first invention group". Therefore, if it is 'Example 2 of Invention Group 1', it will be described as '(Example 1-2)'. The same is true for other invention groups.

[0079] In addition, in fact, although the pixels composed of such a circuit are formed in several columns and rows vertically and horizontally on the substrate, and in some cases, many levels are formed, but since it is self-explanatory and it is troublesome to draw them all, the figure is omitted. This procedure is also the same in other groups of inventions or other embodiments.

[0080] figure 2 A plane (1) showing the structure of one pixel of a conventional liquid crystal panel and an A-A section (2) of a transistor device portion are shown. In this figure, 21 is a transparent pixel electrode. 3 is a pixel electrode. 5 is a liquid crystal layer. 64 is a channel protection film. 65 is an a-Si (amorphous silicon) layer. 66 is an n+a-Si layer. 7 is ...

Embodiment 1-2

[0100] Figure 5 The configuration of Embodiment 1-2 of the present invention is shown.

[0101] In this figure, 8 is the gate line electrode, 7 is the source line electrode, 3 is the pixel electrode, 64 is the channel protective film, 65 is the a-Si layer, 66 is the n+a-Si layer, 86 is the The insulating film between the gate line electrode and the a-Si layer, 76 is the insulating film between the source line electrode and the liquid crystal layer, 5 is the liquid crystal layer, 9 is the opposite electrode, 21 is the transparent pixel electrode, and A is a cross section part of the line.

[0102] In the previous embodiment 1 (Since there is no misunderstanding, the embodiment 1-1 is abbreviated as this. The following is also the same.), although the insulating film is made into two layers, but, by means of this Figure 5 The same effect can be obtained by reducing the thickness of the insulating film between the gate electrode and the liquid crystal layer by patterning as s...

Embodiment 1-3

[0104] Figure 6 The configurations of Embodiments 1-3 of the present invention are shown.

[0105] In this figure, also with Figure 5 Same, 8 is gate line electrode, 7 is source line electrode, 3 is pixel electrode, 64 is channel protection film, 65 is a-Si layer, 66 is n+a-Si layer, 86 is gate line The insulating film between the electrode and the a-Si layer, 76 is the insulating film between the source line electrode and the liquid crystal layer, 5 is the liquid crystal layer, 9 is the opposite electrode, 21 is the transparent pixel electrode, and A is a line showing a section.

[0106] In the case of this structure, the thickness of the liquid crystal layer above the gate line can be made thinner by making the gate line of a predetermined partial thick-film type thicker than the film thickness of the gate line electrode, which can increase the thickness of the gate line. The intensity of the electric field applied to the liquid crystal layer enables rapid transition to ...

Abstract

A high-speed response and wide-view liquid crystal panel for switching liquid crystal called DCB type to bend orientation in a short time, in which a period is provided in which a higher than normal image display time A potential difference is continuously applied between the guard line of the liquid crystal panel and the counter electrode or between the pixel electrode and the counter electrode. Moreover, some ingenious ideas were put into the period of continuously adding the potential difference and injected into the structure of the pixel.

Description

technical field [0001] The present invention relates to a liquid crystal device, and in particular to a start-up technique for driving a liquid crystal device in which the liquid crystal layer is in spray alignment when no voltage is applied and in bend alignment when performing functions such as display. Background technique [0002] (General Background Art) [0003] Liquid crystal device, one of the electric action characteristics of its liquid crystal device is: because each pixel is in a display cycle, if it is bright, it will keep bright, if it is dark, it will continue to keep dark, so it is different from that in a display cycle. Compared with a cathode ray tube, which emits light only for a short period of time, it will become a still picture with less flicker. [0004] However, in recent years, in personal computers, due to the high-speed and large-capacity CPU and memory, it has become possible to easily perform animation processing. For this reason, the improvem...
