Abstract:
A liquid crystal display device comprising a light reflection area formed with a first pixel electrode also used as a reflection film in one portion of a pixel area on one side of a first substrate facing a liquid crystal layer which is sandwiched between the first substrate and a second substrate, and a light transmission area formed with a second pixel electrode of a light transmission property in another portion than the one portion of the pixel area;wherein the first pixel electrode is formed on an upper surface of said one side of the first substrate except for an opening portion of an insulating film in which the opening portion is formed corresponding to the light transmission area, the opening portion of the insulating film tapers towards the upper surface of the first substrate and is defined by a taper formed on a side wall of the insulating film, and at least one portion of the taper is not covered with the first pixel electrode, but is exposed, and the insulating film has a light absorption property in at least the taper portion, and an opening width of a upper face of the opening portion is set as A and an opening width of a lower face of the opening portion is set as B, A and B satisfy a relation of 100%>B/A&gE;90%.
