Abstract: A display device includes: an array substrate; a counter substrate; a liquid crystal layer between the array substrate and the counter substrate; and a light source. The array substrate includes: signal lines; scanning lines; a grid-shaped organic insulating layer that extends along the scanning lines and the signal lines and overlies the scanning lines and the signal lines; pixel electrodes provided in regions surrounded by the scanning lines and the signal lines; and a first orientation film that covers the pixel electrodes. A portion of each pixel electrodes overlaps a slant surface of the organic insulating layer. The counter substrate includes: a common electrode overlapping the respective pixel electrodes; a protective film that has an insulating capability and a light transmitting capability and covers a side of the common electrode facing the array substrate at least in the display region; and a second orientation film that covers the protective film.
