Abstract

On an opposite substrate, such a protrusion that is not contact with an array substrate is disposed. Alternatively, on the array substrate, such a protrusion that is not contact with the opposite substrate is formed of the same material as a spacer. Still alternatively, a large wall-like spacer is disposed on the array substrate. This reduces an amount of liquid crystal sandwiched by the substrates, and thus suppresses generation of low-temperature bubbles in the liquid crystal.

Claims (23)

1. A liquid crystal display device, comprising:

an array substrate on which a plurality of pixel electrodes are disposed in a matrix;

an opposite substrate disposed opposite the array substrate, wherein on the opposite substrate, colored layers of color filters are formed in positions corresponding to the plurality of pixel electrodes;

a single adhesive agent seamlessly disposed between the array substrate and the opposite substrate as so to surround a display region;

a liquid crystal layer sandwiched by the array substrate and the opposite substrate in the display region; and

a wall-shaped structure disposed on a surface, adjacent to the liquid crystal layer, of a first one of the array substrate and the opposite substrate, and extending parallel to the surface of the first one of the array substrate and the opposite substrate,

wherein the wall-shaped structure is separated from a second one of the array substrate and the opposite substrate and from all solid structures attached to the second one of the array substrate and the opposite substrate, and comprises portions extending from the colored layers, the extended portions having lengths substantially the same as lengths of long sides of the colored layers.

2. The liquid crystal display device according to claim 1 , wherein

a light-shielding layer for shielding light in gaps is formed between adjacent two colored layers, and

the structure is disposed on the light-shielding layer.

3. The liquid crystal display device according to claim 1 , wherein a location of the structure corresponds to a location of a wire on the array substrate.

4. A liquid crystal display device, comprising:

an array substrate comprising

a plurality of pixel electrodes disposed in a matrix, and

a storage capacitor line;

an opposite substrate disposed opposite the array substrate and separated from the array substrate by a gap;

a single adhesive agent seamlessly disposed between the array substrate and the opposite substrate as so to surround a display region;

a liquid crystal layer sandwiched by the array substrate and the opposite substrate in the display region; and

a wall-shaped structure disposed on a surface, adjacent to the liquid crystal layer and on the storage capacitor line, of a first one of the array substrate and the opposite substrate, and extending parallel to the surface of the first one of the array substrate and the opposite substrate,

wherein the height of the structure is the same as a length of the gap, and a length of the structure is greater than three times the length of a short side of a pixel.

5. The liquid crystal display device according to claim 4 , wherein

the gap is a first gap, and

the wall-shaped structure is provided with a second gap.
