Zusammenfassung: | To provide a display device that can easily secure luminance in a predetermined range.SOLUTION: A display device comprises: a light source that emits light; a light guide member 4; a light guide plate 9; a display panel; and a light adjustment part 7. The light guide member 4 has a light incidence surface 40 into which light emitted from the light source is injected; and a light emission surface 41 that emits the light injected into the light incidence surface 40. The light guide plate has a first surface into which light emitted from the light emission surface 41 of the light guide member 4 is injected and a second surface that emits the light injected into the first surface. The display panel has light transmissivity and is positioned facing the second surface of the light guide plate. The light adjustment part 7 is provided between the light emission surface 41 of the light guide member 4 and the display panel in a channel of light, and attenuates the light emitted from the light emission surface 41 of the light guide member 4.SELECTED DRAWING: Figure 1
【課題】所定範囲内の輝度を確保しやすい表示装置を提供する。【解決手段】表示装置は、光を出射する光源と、導光部材4と、導光板9と、表示パネルと、光調整部7とを備える。導光部材4は、光源から出射された光が入射される入射面40、及び入射面40に入射された光を出射する出射面41を有する。導光板は、導光部材4の出射面41から出射された光が入射される第1面、及び第1面に入射された光を出射する第2面を有する。表示パネルは、透光性を有し、導光板の第2面に対向して位置する。光調整部7は、光の経路において導光部材4の出射面41と表示パネルとの間に設けられており、導光部材4の出射面41から出射された光を減衰させる。【選択図】図1 |
