Problems solved by technology

[0033] However, when the above-mentioned conventional liquid crystal display panels 10A and 10B are used, light leaks from between the light-shielding black matrix 22 and the cut surface of the glass.
Therefore, when the liquid crystal display device is viewed from an oblique direction, there is a problem that the leaked light degrades the display quality.

Abstract

In a liquid crystal display apparatus having a backlight disposed behind a liquid crystal display panel 10 , the liquid crystal display panel 10 has first and second substrates 11 and 21 disposed to face each other. The second substrate 21 has a common electrode 20 laid in a display area 12 thereon. The second substrate 21 further has a light-shielding inner black matrix 22 laid around the display area 12 and a light-shielding electrically insulated black matrix 22 A, 22 B, and 22 C laid outside the inner black matrix 22 and electrically separated from the inner black matrix 22 and the common electrode 19 . The liquid crystal display panel 10 is held, at the periphery thereof, by metal support frames 32 and 33.

Description

technical field [0001] The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device having a light-shielding black matrix (BM) at an edge portion of a liquid crystal display panel. Background technique [0002] The liquid crystal display panel is formed by arranging two transparent substrates on which electrodes and the like are formed facing each other, and bonding the periphery of the transparent substrates with a sealing material. The liquid crystal is encapsulated in the space formed by the transparent substrate and the sealing material. For example, in the case of an active matrix-driven liquid crystal display panel, signal lines and scanning lines are arranged in a matrix on one substrate. A thin film transistor is formed near the intersection of the signal line and the scanning line, and a pixel electrode connected to the thin film transistor is formed in the region surrounded by the signal line and the s...
