Embodiment 1

[0041]

[0042] Fig. 2 is a plan view showing an embodiment of the liquid crystal display device of the present invention, and one part thereof is represented by an equivalent circuit.

[0043] In this figure, there are a pair of transparent substrates SUB1 and SUB2 arranged opposite to each other with a liquid crystal sealed therein by a sealing material SL also serving as a fixation of the other transparent substrate SUB2 to the one transparent substrate SUB1.

[0044] On the surface of the liquid crystal side of the above-mentioned one transparent substrate SUB1 surrounded by the sealing material SL, gate signal lines GL extending in the x direction and arranged side by side in the y direction are formed, and gate signal lines GL extending in the y direction and arranged in the x direction are formed. Drain signal lines DL arranged side by side.

[0045] A region surrounded by each gate signal line GL and each drain signal line DL constitutes a pixel region, and a matrix-...

Embodiment 2

[0077] FIG. 7 is a diagram showing another embodiment of the image display device of the present invention, corresponding to FIG. 1 .

[0078] Compared with the case of FIG. 1 , the structure is different in that part of the dummy wiring DLY is electrically connected to the adjacent drain signal line DL via the connection portion JK.

[0079] Accordingly, the potential in the dummy wiring DLY is made equal to the potential of the drain signal lines DL located on the side of the drain signal line DL group, thereby stabilizing the potential of the dummy wiring DLY.

[0080] According to this, the electric spark generated by static electricity can surely be caused by the dummy wiring DLY.

[0081] At this time, the line width of the drain signal line DL is generally smaller than that of the data transfer signal line DTL. Furthermore, the line width of the dummy wiring DLY is preferably set to 3 / 4 to 5 / 4 of the line width of the drain signal line DI.

[0082] This is for bringin...

Embodiment 3

[0084] FIG. 8 is a diagram showing another embodiment of the image display device of the present invention, corresponding to FIG. 7 .

[0085] 7, the dummy wiring DLY is connected to the adjacent drain signal line DL, but the connecting portion JK is located at the end of the liquid crystal display AR side, not at the surrounding side of the transparent substrate SUB1.

[0086] With such a configuration, disconnection due to sparks in the dummy wiring DLY can be caused to occur close to the liquid crystal display portion AR. This is because if a disconnection of the dummy wiring DLY occurs on the peripheral side of the transparent substrate SUB1, so-called galvanic corrosion occurs from the disconnection, and the galvanic corrosion may further develop from there.

[0087] In addition, the side of the dummy wiring DLY close to the liquid crystal display AR is covered with the sealing material SL, and even if a disconnection occurs, it is difficult to cause electrical corrosion ...

Abstract

In the present invention, when one signal line group and another signal line group which differs from one signal line group in length are arranged adjacent to each other, a disconnection due to static electricity which is caused by a spark generated between a signal line of one signal line group and a signal line of another signal line group which are arranged adjacent to each other can be prevented. The image signal line is specifically configured such that, on a substrate, a first signal line group in which a plurality of first signal lines are arranged in parallel and a second signal line group in which a plurality of second signal lines are arranged in parallel in a region arranged adjacent to the first signal line group are formed and dummy lines are arranged between the first signal line group and the second signal line group.

Description

technical field [0001] The present invention relates to an image display device, for example, an image display device of the so-called active matrix type. Background technique [0002] For example, an active matrix type liquid crystal display device is provided with a gate signal line arranged side by side in one direction in its panel to supply a scanning signal to a pixel group composed of pixels, and a gate signal line for supplying the scanning signal. The pixel provides a drain signal line for an image signal. [0003] Each pixel is formed with a switching element that operates by supplying a scanning signal, a pixel electrode that supplies a signal from a drain signal line via the switching element, and a pixel electrode that generates an electric field that controls the light transmittance of the liquid crystal between the pixel electrode and the pixel electrode. opposite electrode. [0004] The supply of scanning signals to the gate signal lines and the supply of i...
