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: To improve the reliability of a liquid crystal display device, a liquid crystal display device includes a first substrate a second substrate opposing the first substrate, a liquid crystal layer arranged between the first and second substrates, and a sealing section arranged around the liquid crystal layer. The sealing section includes a member arranged around the liquid crystal layer and extending along an outer edge of the liquid crystal layer in a plan view and a sealing material arranged on both adjacent sides of the member and continuously surrounding a periphery of the liquid crystal layer in a plan view. Further, the first substrate has an oriented film formed on a back surface and a part of the sealing material overlaps a peripheral edge of the oriented film in a thickness direction on a side of the liquid crystal layer of the member.

Abstract: A liquid crystal display device has a liquid crystal display panel that includes a thin-film transistor (TFT) substrate having pixels formed thereon in a matrix pattern and a counter substrate, the two substrates having liquid crystal sandwiched therebetween to constitute a display area having a periphery encircled by a frame area. The display area has a first axis and a second axis perpendicular to the first axis. The liquid crystal display panel is curved along the first axis. The gap between the TFT substrate and the counter substrate is determined by columnar spacers formed on the counter substrate in a manner corresponding to positions of a black matrix over the counter substrate. The center of each of the columnar spacers is displaced in the first axis direction from the center of each of the corresponding positions of the black matrix.
