An electronic device includes a casing having a display part (2) provided with an image display panel (1), a operation part (4) provided with operation keys (3), and a joint part (5) that connects together the display part and the operation part, and a lightguide plate (6) disposed in the casing. The lightguide plate is an edge-light type lightguide plate having a display illuminating part (6a) illuminating the image display panel, a key illuminating part (6b) illuminating the operation keys, and a connecting part (6c) that connects together the display illuminating part and the key illuminating part and that guides light therebetween. The lightguide plate is deformable in accordance with the deformation of the casing.

A display apparatus includes an image display body having a front surface that rewritably displays image information and a light unit that illuminates the front surface of the image display body. The light unit has a light source and a light-transmitting sheet-shaped first lighting member superimposed over the front surface of the image display body. The first lighting member receives light from the light source and emits the light toward the front surface of the image display body to illuminate the front surface.
