Abstract
A liquid crystal display panel including two substrates combined together through a sealing material applied to a peripheral portion thereof. A liquid crystal is sealed between the substrates, and there is a picture-frame area on the substrates, outside a display area and inside a region where the sealing material is formed. A light-shield film is formed in the picture-frame area in the form of a frame surrounding the display area, wherein the light-shield film does not overlap the sealing material. A first conductive film is formed in the picture-frame area on either of the substrates, outside the light-shield film, in the form of a continuously connected frame surrounding the display area and in the same layer as a pixel electrode formed at each pixel in the display area. A second conductive film is formed on the other of the substrates, facing the first conductive film.
