Abstract: A liquid crystal display panel has an electric wiring provided at least on one of a pair of substrates, a seal member, applied to the substrate so as to partially cross the electric wiring, the seal member being made of a ultraviolet ray hardening resin or a ultraviolet ray hardening resin used in combination with heat hardening, wherein the electric wiring has a line width narrower in an area where the seal member crosses the electric wiring than in an area where the seal member does not cross the electric wiring. With the arrangement, when the ultraviolet ray is externally projected onto the seal member from the substrate side, the substrate being provided with the electric wiring, the ultraviolet ray can be fully projected even onto the seal member on the electric wiring which has a narrow line width. It is thus avoided that the liquid crystal orientation is disturbed due to the inadequate hardening of the seal member and the inadequate filling of the liquid crystal occurs.
