Abstract

A liquid crystal display device has a first substrate, a second substrate facing the first substrate, and a liquid crystal layer disposed between the first and the second substrates. The first substrate includes a plurality of pixels, each of which includes a thin film transistor and a pixel electrode. The second substrate includes a color filter facing a pixel electrode of one of the pixels, and a black matrix formed on a region except the color filter. The black matrix has an opening that exposes a portion of one of the gate electrodes. External light entering the opening is reflected from the gate electrode.
