ABSTRACT:
A semi-transparent type liquid crystal display device includes circuit array substrate AR, counter substrate CT and liquid crystal layer LQ held between circuit array and counter substrates AR and CT. The alignment of liquid crystal layer LQ is also controlled by circuit array and counter substrates AR and CT. Circuit array substrate AR has transparent and reflective electrode films8and9at pixel regions. Transparent electrode films8to allow light from a rear light source to pass are lower in level than the reflective electrode films9to reflect ambient incident light. Counter substrate CT is provided with recesses RS corresponding to the transparent electrode films8of circuit array substrate AR to make the thickness of liquid crystal layer LQ thicker at transparent electrode films8than at reflective electrode films9.
