A display apparatus is provided which realizes high display quality without inclusion of bubbles when a protective cover is bonded over the display surface of the display panel with a transparent adhesive sheet therebetween. A display surface of a display panel and a protective cover are bonded with first and second transparent adhesive sheets. The first transparent adhesive sheet has a cross-sectional area vertical to the thickness direction that is formed smaller than the opening area of an opening of a frame, and it is provided within the opening. Then, a bonding member is charged into a gap formed by the frame, display panel, first transparent adhesive sheet, and second transparent adhesive sheet, so as to bond the frame, display panel, first transparent adhesive sheet, and second transparent adhesive sheet.

Display apparatus

A display device includes a display panel having a display plane, a frame having an opening formed at an area corresponding to the display plane, for holding the periphery of the display panel, a protecting cover for protecting the display plane, and two transparent adhesive sheets arranged in the gap between the display plane and the protecting cover.

Display device

A lamp lighting terminal which is a conductive pad connected to a power supply terminal of a lamp is mounted on a surface opposite to a light emitting surface of a flat light source apparatus. Then, a terminal of a inspection device is brought into contact with the lamp lighting terminal to light up a liquid crystal display apparatus, thereby allowing inspection to be carried out. The flat light source apparatus may be provided with a light guide inputting lights from a light source through the side to output the light through one surface. In this configuration, inspection work at the time of lighting inspection of a liquid crystal display is simplified, and a high-quality liquid crystal display can be obtained.
