Abstract
In manufacturing a liquid crystal display element which includes a black matrix, in curing an ultraviolet curing sealing material after filling liquid crystal using a dropping injection method, there has been a possibility that a radiation quantity of ultraviolet rays to the sealing material is insufficient and hence, the curing is not sufficiently performed thus largely lowering the reliability of the liquid crystal display element. According to the present invention, an overlapping width of a frame-like sealing material and a black matrix on a peripheral portion along a display region is suppressed to 0.2 mm or less, or a region of the black matrix which is overlapped to the frame-like sealing member is patterned to include a light transmitting portion.
