PROBLEM TO BE SOLVED: To provide an active matrix liquid crystal display, which protects a color filter and a black matrix without reducing the transmittance, and easily and precisely prescribe the gap between a TFT substrate and a counter substrate, without providing a spacer and its manufacturing method. SOLUTION: In a liquid crystal display device, having a CF(color filter) on TFT structure where a color filter 10, a black matrix(BM) 11 in the upper layer of a TFT and the upper layer of a data line 7, and a pixel electrode are provided on the TFT substrate having a gate line 5 and the data line 7, a first thick overcoat layer and a second thin overcoat layer are arranged on the BM 11, and only the second thin overcoat layer is arranged on the CF 10 in a display area, and the BM 11 is surely protected by the first overcoat layer, with attenuation of incident light being suppressed by the second overcoat layer to improve the effective numerical aperture.
