Abstract:
1. A liquid crystal display device comprising a reflection region for reflecting incident light toward a display surface, wherein the reflection region includes a metal layer, an insulating layer formed on the metal layer, a semiconductor layer formed on the insulating layer, and a reflective layer formed on the semiconductor layer; a plurality of recesses are formed in the metal layer; recesses/protrusions, reflecting a shape of the metal layer, are formed in the reflective layer in the reflection region; a plurality of protrusions of the metal layer, each having a bottom surface, an upper surface and a slope, are formed between the plurality of recesses of the metal layer; and a width a of the bottom surface of at least one of the plurality of protrusions in the metal layer satisfies where a denotes the width of the bottom surface of each of the plurality of protrusions, x a thickness between the bottom surface and the upper surface, θ a tilt angle of the slope with respect to the bottom surface, and y a total thickness of the insulating layer, the semiconductor layer and the reflective layer.
