Abstract: A display device includes a first substrate, a light-emitting element on the first substrate, a second substrate opposed to the first substrate, a first protruding structure surrounding the light-emitting element on a surface of the second substrate opposed to the first substrate, and a light-shielding film overlapping the first protruding structure between the first substrate and the second substrate, wherein a supplementary angle of an inclination angle of a side surface of the first protruding structure is 30 degrees or more and 90 degrees or less. In addition, the display device further includes a reflective film on the side surface of the first protruding structure. Furthermore, the light-shielding film is located between the first protruding structure and the second substrate. Besides, a surface of the first protruding structure on a side of the second substrate is smaller than the light-shielding film.

Abstract: To address static electricity on a flat panel display device and to implement a narrow frame of the flat panel display device. A liquid crystal display device (20) includes a counter substrate (22), a TFT substrate (21), and an upper polarizer (23). The TFT substrate (21) includes a terminal portion (30) projecting more outward than the edge of a counter substrate (22), and a ground pad (32) disposed on a surface of the terminal portion (30), the surface being on the side closer to the counter substrate (22). The upper polarizer (23) includes a pad facing portion (33) that overlaps the ground pad (32) at a position more outward than the edge of the counter substrate (22). The liquid crystal display device (20) further includes an electrically conductive member (34) filled in the gap between the ground pad (32) and the pad facing portion (33).
