<P>PROBLEM TO BE SOLVED: To provide a display capable of keeping lighting brightness, even when the display is provided tilted with respect to a driver. Ž<P>SOLUTION: The display includes a light-receiving-type display member 3, an optical waveguide 4 provided along a rear face of the display member 3, and a light source 5 for illuminating the display member through the optical waveguide 4. The optical waveguide 4 includes an emitting surface 41, a rear face 42 and side faces 43-46. A plurality of reflecting parts 47, including a groove with a V-shaped cross section, are formed on the rear face 42. The light source 5 is provided to be capable of making irradiation light incident to the optical waveguide 4 through the side face 43. In such a display, the light source 5 is provided above or below the optical waveguide 4, and the reflecting part 47 has a groove with a V-shaped cross section formed of a first face 471 and a second face 472, wherein the length of the first face 471 is formed longer than the second face 472.
