Liquid crystal display device
View Patent ↗A display device includes a display panel having a display region and a peripheral region, the display panel including a TFT substrate, a counter substrate fixed to the TFT substrate by seal material formed at the peripheral region, and liquid crystal interposed between the TFT substrate and the counter substrate. The TFT substrate includes an inorganic film and an organic film, with first column spacers being formed on the counter substrate. The organic film includes a first part which has an island-like shape formed at the peripheral region and a second part formed at the display region, and the seal material covers at least one of the first column spacers and the first part of the organic film, and is in contact with the inorganic film. The first part of the organic film is separated from the second part of the organic film of the organic film.
1. A liquid crystal display device comprising:
a liquid crystal display panel having a display region and a peripheral region around the display region, the display panel including a first substrate, a second substrate fixed to the first substrate by a seal material formed at the peripheral region, and liquid crystal interposed between the first substrate and the second substrate;
wherein the first substrate has first protrusions and second protrusions in the peripheral region;
wherein the first protrusions are arranged in an extending direction of the seal material, and the second protrusions are arranged in the extending direction of the seal material;
wherein the seal material covers the first protrusions and the second protrusions in a plan view;
wherein the second protrusions are closer to an edge of the first substrate than the first protrusions,
wherein one of the second protrusions is not provided on a line that extends from a center of one of the first protrusions to the edge of the first substrate and intersects the extending direction of the seal material, in the plan view, and
wherein another one of the second protrusions is provided on the line that extends from a center of another one of the first protrusions to the edge of the first substrate and intersects the extending direction of the seal material, in the plan view.
2. The liquid crystal display device according to claim 1 , wherein
the first substrate further has third protrusions in the peripheral region;
the third protrusions are arranged in the extending direction of the seal material, and
the third protrusions are closer to the edge of the first substrate than the second protrusions.
3. The liquid crystal display device according to claim 2 , wherein
one of the second protrusions is not provided on a line that extends from a center of one of the third protrusions to a direction opposite to the edge of the first substrate and intersects the extending direction of the seal material, in the plan view, and
another one of the second protrusions is provided on the line that extends from a center of another one of the third protrusions to the direction opposite to the edge of the first substrate and intersects the extending direction of the seal material, in the plan view.
4. The liquid crystal display device according to claim 3 , wherein
one of the first protrusions is located on a same straight line as one of the third protrusions, in the plan view.
5. The liquid crystal display device according to claim 1 , wherein
a width of the second protrusions in the width direction of the seal material is larger than a width of the first protrusions in the width direction of the seal material.
6. The liquid crystal display device according to claim 5 , wherein
the width of the first protrusions in the width direction of the seal material and a width of the third protrusions in the width direction of the seal material are same.
7. The liquid crystal display device according to claim 1 , wherein the second substrate includes spacers provided on the second substrate, and
the spacers do not overlap with a gap between the second protrusions, in the plan view.
