Abstract
A liquid crystal device 1 includes a transparent first substrate 10 with a first transparent electrode 11 formed on the surface thereof, a transparent second substrate 20 with a second transparent electrode 21 is formed thereon, and a liquid crystal layer 50. A light reflecting layer 4 defining the reflective display region 31 and the transmissive display region 32 is formed on each pixel region 3. A layer-thickness adjusting layer 6 where a region corresponding to the transmissive display region 32 constitutes an opening 61, is formed on the upper layer side of the light reflecting layer 4. In the layer-thickness adjusting layer 6, the boundary portion of the reflective display region 31 and the transmissive display region 32 constitutes an inclined surface 60, and a light shielding film 9 is two-dimensionally superimposed on this boundary region.
