A TFT-LCD having a first glass substrate provided for fabricating transistors, a second glass substrate provided for fabricating a color filter, and a liquid crystal layer interposed between the second and first glass substrates. The TFT-LCD comprises the following components. A color filter is formed beneath the second glass substrate which has plural color filter elements and a first black matrix, wherein each grid pattern of the first black matrix is disposed to surround a color filter element. And the color filter element formed beneath the second glass substrate extends outward to surfaces of the first black matrix. A common electrode is formed beneath the color filter, wherein a part of the common electrode, the pixel units, and the first black matrix are overlapped to have a downward protruding structure. A second black matrix is formed on the first glass substrate, wherein each grid pattern of the second black matrix is disposed under inner edges of the each grid pattern of the first black matrix. And a pixel electrode is formed on the first glass substrate and located under the color filter element, wherein the pixel electrode extends outward to overlap the second black matrix to have an upward protruding structure.
