Abstract:
1. A TFT-LCD having a first glass substrate with a plurality of transistors, a second glass substrate, and a liquid crystal layer interposed between the second and first glass substrates, the TFT-LCD comprising: a plurality of color filter elements and a first black matrix formed beneath the second glass substrate, wherein the first black matrix having a grid pattern to define a pixel unit region, the color filter elements covering the pixel unit region and being overlapped with the first black matrix for composing a first protruding structure; a common electrode formed beneath the second glass substrate and covering the first protruding structure; a second black matrix, an insulating layer, a insulating block, and a passivation layer sequentially formed on the first glass substrate and overlapped for composing a second protruding structure; and a pixel electrode formed on the first glass substrate corresponding to the pixel unit region and covering the second protruding structure, wherein the second black matrix is made of the same material of a gate electrode of the transistor, and the insulating block is made of the same material of an etching stopper of the transistor.
