Display device
View Patent ↗A first substrate includes a first insulating substrate. A first organic insulating film is arranged on the first substrate in a circumference area outside an active area. The first organic insulating film includes a first surface and a first concave portion in the circumference area. A second substrate includes a second insulating substrate. A circumference color filter is laminated on a circumference shield layer and includes a second concave portion arranged facing the first concave portion. The second concave portion spreads toward the first substrate. A second organic insulating film covers the circumference color filter and includes a second surface and a third concave portion covering the second concave portion. A seal material is arranged between the first surface and the second surface, and between the first concave portion and the third concave portion to attach the first substrate and the second substrate.
