Abstract

A liquid crystal display device includes an array substrate, a counter-substrate which is disposed to be opposed to the array substrate, a liquid crystal layer which is formed of a liquid crystal material which is held between the array substrate and the counter-substrate, and a sealant which bonds the array substrate and the counter-substrate. The array substrate includes a pixel electrode having a slit, and a counter-electrode which is opposed to the pixel electrode via an interlayer insulation film. The counter-substrate has a shield electrode on an outer surface thereof. The shield electrode is disposed such that an end portion thereof along at least one side of the counter-substrate, is exposed on the outer surface of the counter-substrate.

Claims (14)

1. A method of manufacturing a liquid crystal display device comprising an array substrate, a counter substrate which is disposed to oppose the array substrate, and a liquid crystal layer held between the array and counter substrates, the method comprising:

providing a first mother substrate having a plurality of array substrates, each of the array substrates comprising:

a display element section having a plurality of pixel electrodes and a counter electrode, and

a mounting section located outside of the display element section,

providing a second mother substrate having a plurality of counter substrates corresponding to the array substrates and having a first side facing the liquid crystal layer;

bonding the first and second mother substrates via a sealant;

forming a plurality of shield electrodes on an outer surface of the second mother substrate, the outer surface being on a second side of the second mother substrate, the second side being opposite the first side; and

cutting a portion of the outer surface not covered by the shield electrodes, and removing a region of the second mother substrate, the region being opposed to the mounting section, to form the liquid crystal display device.

2. The method of claim 1 , wherein the shield electrodes are formed by a mask sputtering process.

3. The method of claim 1 , wherein the display element section further comprises a switching element.

4. The method of claim 1 , wherein one of the shield electrodes comprises a terminal portion led out to one side of the counter substrate.

5. The method of claim 4 , wherein at least one of the array substrates comprises a ground potential wiring line, and

the method further comprises electrically connecting the terminal portion of the shield electrode to the ground potential wiring line, after the cutting.

6. The method of claim 1 , further comprising electrically connecting a terminal portion of the shield electrodes to a metal frame after the cutting.
