Abstract
Disclosed is a liquid crystal display (LCD) device equipped with a resin black matrix, capable of preventing the light leakage phenomenon by improving an OD (optical density) value of the resin black matrix. The LCD device includes an array substrate formed with a thin film transistor and a pixel electrode, a color filter substrate aligned opposite to the array substrate and formed with a resin black matrix and a color filter, a liquid crystal layer aligned between the array substrate and the color filter substrate, and lower and upper polarizing plates attached to outer surfaces of the array substrate and the color substrate and having transmission axes extending in the same direction. The resin black matrix has a transmission axis perpendicular to the transmission axes of the lower and upper polarizing plates so that the resin black matrix has a polarizing function.
