Abstract
A normally-black active-matrix-type liquid crystal display device comprises a first substrate having color layers of three or more colors and a second substrate on which an active-matrix array is formed. The first substrate has a structure, which is devoid of a black matrix, in which the color layers are stacked in a frame portion surrounding the display area. A first light-shielding layer in which color layers of three of more colors are stacked is formed on the frame portion on a side of the display area from which scanning lines are led out and on a side of the display area from which data lines are led out, from among four sides of the display area. A second light-shielding layer in which color layers of two colors are built up is formed on the frame portion on at least one side of the other remaining sides of the display area.
