Liquid crystal display device
View Patent ↗In a first substrate, a first organic insulating film is arranged in an active area, and includes a first surface and a first concave portion in a peripheral area outside the active area. The first concave portion is located more close to a substrate end side than the first surface. In a second substrate, a shield layer is arranged in the peripheral area facing the first substrate. A second organic insulating film includes a second surface facing the first surface and a second concave portion facing the first concave portion. The second organic insulating film overlaps the shield layer in the peripheral area. A pillar-shaped spacer is arranged between the first surface and the second surface in the peripheral area. A seal material contains the pillar-shaped spacer and is arranged between the first surface and the second surface, and between the first concave portion and the second concave portion.
