Display panel and liquid crystal display device having particular sealing structure
Abstract:
The present invention provides a display panel that can improve the adhesion strength of a sealing member and that can reduce moisture permeation caused by an alignment film without performing a treatment to remove the alignment film. A display panel according to the present invention is a display panel having a pair of substrates attached to each other via a sealing member. At least one of the pair of substrates has a configuration in which a transparent resin film and an alignment film are laminated. In the display panel, a side face of an edge of the transparent resin film has a reverse tapered shape; the alignment film is separated at the side face of the edge; and the transparent resin film and the sealing member are attached to each other without having the alignment film therebetween.
