Abstract

Official abstract text for this publication.

An upper frame covers a periphery of a liquid crystal display panel, and a cover plate is bonded onto the upper frame and an upper polarizing plate of the liquid crystal display panel. A step is formed on the cover plate in a portion where the upper frame is bonded to the cover plate. This can reduce a thickness of resin between the upper polarizing plate and the cover plate, thereby reducing an extrusion of the resin in between the cover plate and the upper frame. Thus, a chamfer on a lower side of the cover plate can be reduced in size, and stray light from the lower side of the cover plate can be prevented. This can prevent a white line around a screen.

First claim

Opening claim text (preview).

What is claimed is: 1. A display device comprising an upper polarizing plate applied onto a display panel, an upper frame covering a periphery of the display panel, and a cover plate covering a display surface of the display panel and attached onto the upper frame and the upper polarizing plate by an adhesive material, wherein the cover plate has a step with its thickness reduced in its periphery, and the upper frame is bonded to the cover plate at the step, and wherein a light-blocking printing is applied to the step of the cover plate, and a thickness of the adhesive material between the cover plate and the upper polarizing plate is smaller than a thickness of the adhesive material between the upper frame and the light-blocking printing. 2. The display device according to claim 1 , wherein an inner end of the step of the cover plate is located more inward than an end of the upper polarizing plate and more outward than an end of a display area of the display panel. 3. The display device according to claim 1 , wherein the display panel is a liquid crystal display panel further including a lower polarizing plate, the adhesive material is a UV adhesive material, and a backlight is arranged on a back face of the liquid crystal display panel. 4. The display device according to claim 1 , wherein the display panel is an organic EL display panel. 5. The display device according to claim 1 , wherein the cover plate is made of glass.
