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.
