LIGHT-EMITTING DEVICE

PROBLEM TO BE SOLVED: To suppress phenomena such as change in balance in brightness of illumination light in switching of the illumination light that two light sources emit and color unevenness when the two light sources emit the illumination light simultaneously.SOLUTION: A light-emitting device 10 is characterized in that first and second light sources 14, 15 are arranged which emit illumination light beams 31, 32 differing in color from each other to one slender translucent part 12 that the light-emitting device has on a display surface 11a, and the illumination light beams 31, 32 that the first and second light sources 14, 15 emit respectively are transmitted from the translucent part 12. The first and second light sources 14, 15 are positioned opposite to each other on both sides of a long side 12a of the slender translucent part 12. A light guide part 16 which individually guides the respective illumination light beams 31, 32 that the first and second light sources 14, 15 emit respectively to the slender translucent part 12 are positioned between the first and second light sources 14, 15 and the slender translucent part 12.SELECTED DRAWING: Figure 2 【課題】２つの光源が発する照明光を切り替えたときの、照明光の輝度のバランスの変化や、２つの光源が同時に照明光を発したときの色ムラの発生といった現象を、極力抑制すること。【解決手段】発光装置１０は、表示面１１ａに有している１つの細長い透光部１２に対し、互いに色が異なる照明光３１，３２を発する第１及び第２の光源１４，１５が配置され、この第１及び第２の光源１４，１５がそれぞれ発した前記照明光３１，３２を前記透光部１２から透過する。前記第１及び第２の光源１４，１５は、前記細長い透光部１２の長辺１２ａに対して両側に、対向し合って位置している。前記第１及び第２の光源１４，１５と前記細長い透光部１２との間には、前記第１及び第２の光源１４，１５がそれぞれ発した前記各照明光３１，３２を前記細長い透光部１２へ個別に導く導光部１６が位置している。【選択図】図２
