Abstract: A light emitting device is installed in a display apparatus such as that used in a television set. The light emitting device includes a light source that emits light, a light guiding plate having a light receiving portion that receives light from the light source, and a substrate having a wiring pattern that is electrically connected to the light source. The substrate is bent and disposed so as to cover a space between the light source and the light receiving portion. The light guiding plate emits the received light toward, for example, a liquid crystal panel. The liquid crystal panel displays images by causing each of pixels to transmit or block light irradiated.
