Abstract: In one embodiment, a first substrate includes a gate line extending in a first direction, a source line extending in a second direction orthogonally crossing the first direction, a pixel electrode including a main pixel electrode extending in the second direction, and a first alignment film covering the pixel electrode. A second substrate includes a common electrode having a pair of main common electrodes arranged on both sides sandwiching the main pixel electrode and a second alignment film covering the common electrode. A liquid crystal layer is held between the first alignment film and the second alignment film and includes liquid crystal molecules. The liquid crystal layer is formed of materials having negative dielectric constant anisotropy, and the liquid crystal molecules are initially aligned substantially in parallel with the first direction when electric field is not impressed between the pixel electrode and the common electrode.

Abstract: An object of this invention is to increase the number of liquid crystal display panels obtained from a mother substrate. There is provided a liquid crystal display device including a TFT substrate and a counter substrate bonded together by a seal portion formed along the periphery of the counter substrate, the TFT substrate having a terminal area formed in a portion thereof not opposed to the counter substrate. The TFT substrate has a bank-like organic passivation film formed along the edge of the terminal area. A stepped part is formed on the organic passivation film. The film thickness of the organic passivation film on the edge side of the stepped part is greater than the film thickness inside the stepped part.
