Abstract:
There is provided a CPA-type liquid crystal display device in which deterioration in display quality due to application of stress to a liquid crystal panel is suppressed.A liquid crystal display device according to the present invention includes a first substrate; a second substrate; and a liquid crystal layer of a vertical-alignment type provided therebetween. In each picture element region, a first electrode provided on a side of the first substrate facing the liquid crystal layer includes a solid portion formed of an electrically-conductive film and a non-solid portion in which no electrically-conductive film is formed. The solid portion includes a plurality of unit solid portions each of which is substantially surrounded by the non-solid portion, the plurality of unit solid portions being arranged at least along a first direction. When a voltage is applied, with an oblique electric field generated at an edge of the non-solid portion, the liquid crystal layer within the picture element region forms a liquid crystal domain on each unit solid portion, the liquid crystal domain taking a radially-inclined orientation. The length of the unit solid portion along the first direction is 70 μm or less.
