| description | To provide a light source unit that easily secures luminance in a predetermined range, and a display device that comprises the same.SOLUTION: A light source unit 1 comprises a light source part 3, a first light guide body 42, a second light guide body 43, and a case 5. The light source part 3 emits light. The first light guide body 42 comprises a first incidence surface on which the light emitted from the light source part 3 is incident, and a first emitting surface for emitting the light incident on the first incidence surface. The second light guide body 43 comprises a second incidence surface opposed to the first emitting surface, and on which the light emitted from the first emitting surface is incident, and a second emitting surface for emitting the light incident on the second incidence surface. The case 5 houses the first light guide body 42 and the second light guide body 43. At least one of the second light guide body 43 and the case 5 comprises a gap forming part 7. The gap forming part 7 forms a gap between the first emitting surface of the first light guide body 42 and the second incidence surface of the second light guide body 43.SELECTED DRAWING: Figure 1
【課題】所定範囲内の輝度を確保しやすい光源ユニット及びこれを備える表示装置を提供する。【解決手段】光源ユニット１は、光源部３と、第１導光体４２と、第２導光体４３と、ケース５とを備える。光源部３は、光を出射する。第１導光体４２は、光源部３から出射された光が入射される第１入射面と、第１入射面に入射された光を出射する第１出射面とを有する。第２導光体４３は、第１出射面と対向し第１出射面から出射される光が入射される第２入射面と、第２入射面に入射された光を出射する第２出射面とを有する。ケース５は、第１導光体４２と第２導光体４３とを収容する。第２導光体４３及びケース５の少なくとも１つは、隙間形成部７を有する。隙間形成部７は、第１導光体４２の第１出射面と第２導光体４３の第２入射面との間に隙間を形成させる。【選択図】図１ |
