PROBLEM TO BE SOLVED: To provide a light emitting display device in which irregularities of brightness between attachment positions of respective LEDs arranged side by side along a margin of a light guide plate and positions of gaps between the LEDs hardly exert influence to light emission display of a display plate.SOLUTION: A light emitting display device includes: a light guide plate which arranges a plurality of LEDs side by side to each other leaving an interval and causes a light emission surface to emit light with light of respective LEDs; and a display plate which transmits light from the light emission surface and performs light emitting display. Therein, light of the respective LEDs is made incident to the inside from the margin set as a light incident part of the light guide plate, a plate surface set as the light emission surface is disposed so as to perform surface light emission and the plate surface of the display plate is arranged so as to face the light emission surface of the light guide plate and enlarge an interval between the light emission surface and the plate surface of the display plate as approaching the light incident part side. Because the interval between the light emission surface and the plate surface of the display plate is disposed, irregularities of brightness caused between the neighborhood of optical axis of the respective LEDs and the neighborhood of middle position of the respective LEDs are reduced until reaching the display plate and the light emitting display of the display plate can be performed with more homogeneous brightness as a whole. |
