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.
