Abstract
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.

A display device comprising,
- a TFT substrate,
- a plurality of pixels formed in a matrix on the TFT substrate,
- a first line electrically connected to an outer circuit,
- a counter substrate opposed to the TFT substrate, and
- a black matrix having a slit and formed on the counter substrate,
- wherein the slit is formed to surround a display area where the plurality of pixels are formed,
- wherein the first line has a first portion and a second portion which are formed on different layers,
- wherein the first portion and the second portion are connected by a through hole,
- wherein the through hole is between the slit and the display area in a plan view,
- wherein the second portion extends in a second direction and crosses a portion of the slit,
- wherein the portion of the slit extends in a first direction crossing the second direction, and
- wherein the first portion extends in a direction crossing the first direction and the second direction.
