Patent ID: 8659726

Claim:
A liquid crystal display device comprising: a first substrate and a second substrate between which liquid crystal is interposed; a first electrode and a second electrode formed on the first substrate for applying a voltage for controlling an orientation of the liquid crystal; a transistor having an electrode which is electrically connected to the first electrode; a metal layer formed on the first substrate, the metal layer including a protrusion, a recess, or an aperture; a reflective layer formed above the metal layer in the first substrate, the reflective layer reflecting incident light toward a display surface, wherein, the metal layer is made of a same material as that of a gate electrode of the transistor; and the reflective layer includes a protrusion, a recess, or a level difference which is formed in accordance with the protrusion, recess, or aperture of the metal layer; and under the reflective layer, a semiconductor layer made of a same material as a semiconductor portion of the transistor, the semiconductor layer including a protrusion, a recess, or an aperture, wherein, the reflective layer includes a protrusion, a recess, or a level difference which is formed in accordance with the protrusion, recess, or aperture of the semiconductor layer.
