ABSTRACT:
A liquid crystal display (LCD) device partially or substantially blocks light from a light source from exciting a semiconductor layer. The LCD device includes a substrate, a semiconductor layer, a light-shielding layer, and a light source. The light source directs light toward a lower surface of the substrate. The light-shielding layer is formed between the substrate and the semiconductor layer. Some or all of the light directed towards the semiconductor layer by the light source is blocked by the light-shielding layer.
