Abstract
A display apparatus is constituted by a planar display device and a planar illumination device therefor. A lowering in light quantity at a periphery of the planar illumination device is prevented by inserting a reflection member, such as a reflection frame, having an inside reflection surface along the periphery of the illumination device, or a combination of a scattering means and a transparent sheet member between the display device and the illumination device. A plurality of the display apparatus may be combined to allow an associate movement thereof so as to constitute a composite display apparatus, such as a head-mount display.
