Abstract
A liquid crystal device 1 includes a transparent first substrate 10 having first transparent electrodes 11 on the surface thereof, a transparent second substrate 20 having second transparent electrodes 21, and a liquid crystal layer 50. Pixel regions 3 have a light-reflecting layer 4 defining reflective display regions 31 and transmissive display regions 32. A thickness-adjusting layer 6 having opening 61 defining the transmissive display regions 32 is formed on the light-reflecting layer 4. The thickness-adjusting layer 6 forms slopes 60 at the boundaries between the reflective display regions 31 and the transmissive display regions 32. The top edges 65 of the slopes are aligned with the edges 45 of the light-reflecting layer 4.
