Abstract
A liquid crystal display device including a first substrate 110a, a second substrate 110b placed to face the first substrate, a liquid crystal layer 120 interposed between the first and second substrates, a first electrode 111 formed on the first substrate, a second electrode 131 formed on the second substrate, an interlayer insulating film 115a placed between the first electrode and the first substrate, and a wall structure 115b formed integrally with the interlayer insulating film. The liquid crystal display device has a plurality of pixels each including the first electrode, the second electrode and the liquid crystal layer interposed between the first and second electrodes. A shading region surrounds each of the plurality of pixels, and the wall structure is placed regularly in the shading region. A groove structure 415a may be formed in place of the wall structure.
