Abstract: A liquid crystal display device includes a counter substrate having a glass substrate, a color layer on the glass substrate, an overcoating layer on the color layer, and a counter protrusion and a counter wall protrusion on the overcoating layer. The counter protrusion is located in an image display region. The counter wall protrusion is located in a peripheral region enclosing the image display region. The counter protrusion and the counter wall protrusion are of substantially a same height. A first protrusion distance from the glass substrate to a top of the counter protrusion is shorter than a second protrusion distance from the glass substrate to a top of the counter wall protrusion. According to the liquid crystal display device configured as above, an outer periphery of a display panel does not bend.

Abstract: A liquid crystal display includes a first substrate and a second substrate bonded to each other at their periphery by a sealant, with liquid crystal sealed between the first substrate and a second substrate, and has a display region. The first substrate is formed, between the sealant and an end portion of the display region, with a wall that partitions the liquid crystal into a portion on the display region side and a portion on the sealant side. A gap exists between the tip of the wall and the second substrate side. In the liquid crystal display device, a liquid crystal portion that has been contaminated is restrained from moving into the display region.

Abstract: In one embodiment, a first substrate is provided with first and second main pixel electrodes electrically connected each other extending along a first direction, respectively. A second substrate includes first to third main common electrodes electrically connected each other extending along the first direction, respectively. The first main pixel electrode is arranged between the first and second main common electrodes, and the second main pixel electrode is arranged between the second and third main common electrodes. Four inter-electrode distances are formed. One of the four inter-electrode distances is set to an optimal inter-electrode distance, and one of the four inter-electrode distances is different from at least one of the other three inter-electrode distances. Herein, the optimal inter-electrode distance is defined as follows: in a range of voltage which is applied between the electrodes, more than 90% of a peak transmissivity is obtained by the optimal inter-electrode distance.
