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: In one embodiment, a liquid crystal display device includes a first substrate and a second substrate. The first substrate includes a first gate line and a second gate line respectively extending in a first direction. A main pixel electrode is arranged between the first gate line and the second gate line and extending in a second direction orthogonally crossing the first direction. A pair of sub-common electrodes respectively faces the first gate line and the second gate line through an insulating layer and extends in the first direction. The second substrate includes a main common electrode electrically connected with the sub-common electrode and arranged on both sides sandwiching the main pixel electrode. A liquid crystal layer is held between the first substrate and the second substrate.
