PURPOSE:To suppress deterioration in OFF characteristics of a thin film transistor(TFT) deterioration in display quality due to light reflection by forming the black matrix of a metallic film provided at its edge part and a dark-color organic material film. CONSTITUTION:This liquid crystal display device is constituted by separately forming and superposing layers on the sides of lower and upper transparent glass substrates SUB1 and SUB2 one over the other, and then charging liquid crystal LC between the both. On the side of the upper transparent glass substrate SUB2, the black matrix BM is provided as a light shield film so as to make contours of respective picture elements clear and also prevent the OFF characteristics of the TFT from deteriorating. The black matrix BM consists of two layers of the metallic film provided at the edge part constituting the contour and the black organic material film provided inside the metallic film. The metallic film of the black matrix BM contains, for example, Cr, Ni, Al, etc., having high light shielding property and the organic material film is formed by coloring a dyed base material such as acrylic resin with a black dye. |
