A LCD device that receives curing light sufficiently to thereby realize approximately uniform curing of the material of the sealing member without eliminating the conductive light-blocking members. A first substrate has a display area and a peripheral area located to surround the display area. The display area includes pixels arranged regularly. The peripheral area includes a sealing member, wiring lines connected to the pixels, and conductive light-blocking members. A second substrate is coupled with the first substrate. A liquid crystal layer is formed between the first and second substrates. The sealing member is formed to overlap with the wiring lines and the light-blocking members in such a way that a non-overlapping area of the sealing member with the wiring lines and the light-blocking members is equal to 25% per unit area of the sealing ember or greater.
