Abstract: A liquid crystal display device includes a bank on a first substrate and surrounding an image display area, a first alignment film on the first substrate, a second alignment film on a second substrate, and a sealing member to seal the liquid crystal material between the first and the second alignment films. The bank has a shape in which a slope of an inside surface standing from an inner peripheral lower end on a side of the image display area is steeper than a slope of an outside surface standing from an outer peripheral lower end on an opposite side to the image display area. The first alignment film contacts the inside surface of the bank and is provided in the image display area. The sealing member passes over the outside surface of the bank in a direction toward the inside surface and overlaps the bank.

Abstract: According to one embodiment, a display device includes a first substrate, a second substrate, and a liquid crystal layer. The first substrate includes first pixels overlapping with a display area and second pixels overlapping with a surrounding area, color filters corresponding to each of the first pixels, and a first light-shielding layer including an aperture overlapping with each of the first and second pixels. The second substrate includes a second light-shielding layer surrounding the display area. The width of the first light-shielding layer arranged at a position overlapping with an end portion of the display area is greater than a width between apertures overlapping with each of first pixels adjacent to each other.

Abstract: A liquid crystal display device includes a thin film transistor (TFT) substrate and a counter substrate that are disposed opposite to each other with a liquid crystal layer in between. The TFT substrate has, an organic passivation film formed covering the TFT, and a pixel electrode and a common electrode formed on the organic passivation film, the organic passivation film having a through-hole to connect the pixel electrode and the TFT. A columnar spacer is formed on the counter substrate to define a distance between the TFT substrate and the counter substrate. A planarization film made of resin is formed in the through-hole. A recess is formed in the through-hole by a surface of the planarization film and a sidewall of the through-hole. A tip end of the columnar spacer exists in the recess.
