Publication number: 20200041833Abstract: A black matrix is formed to an edge of a counter substrate. Then, a BM slit, which is an area where the black matrix is not present, is formed in the periphery of a seal material in order to prevent water or moisture from penetrating from the interface between the counter substrate and the black matrix. Then, a light shielding metal is formed in a layer other than a lead line layer, on the side of a TFT substrate, in order to prevent light from leaking from the BM slit. With this structure, it is possible to prevent the light from leaking from the BM slit around a screen. As a result, the degradation of the contrast can be prevented in the periphery of the screen.Type: ApplicationFiled: October 14, 2019Publication date: February 6, 2020Inventor: Syou YANAGISAWA
