HIGH APERTURE RATIO LIQUID CRYSTAL DISPLAY WITHOUT BLACK MATRIX

摘要

PURPOSE: A high aperture ratio liquid crystal display without a black matrix is provided to prevent color mix between adjacent pixel areas without forming the black matrix, thereby preventing an aperture ratio from decreasing due to the black matrix. CONSTITUTION: A plurality of gate bus lines and data bus lines(2) are crossly arranged on a first glass substrate(1) of a lower substrate(10). Thin film transistors are formed at cross points. A pixel electrode(6) formed of an ITO(Indium Tin Oxide) material is formed in each pixel area and extended to the upper parts of the gate bus lines and the data bus lines. R, G, and B color filters(14) are formed on a second glass substrate(11) of an upper substrate(20), corresponding to the pixel areas. An overcoat layer(16) is formed on a front surface of the second glass substrate, having concave patterns at surface parts corresponding to boundary parts between the pixel areas. A relative electrode(18) formed of the ITO material is formed on the overcoat layer. A liquid crystal layer(30) is interposed between the lower substrate and the upper substrate.
