To provide a technique of improving the performance of a display device.SOLUTION: A display device includes a substrate 10 having a first front surface and a first rear surface on the opposite side of the first front surface, a substrate 20 having a second rear surface facing the first front surface and a second front surface on the opposite side of the second rear surface, a liquid crystal layer LQL disposed between the first front surface of the substrate 10 and the second rear surface of the substrate 20, a light guide plate 40 that is fixed with adhesion onto the second front surface of the substrate 20 through an adhesive layer 41, and a light source part 50 disposed at a position facing a first side surface of the light guide plate 40. The refractive index of the light guide plate 40 is lower than that of the adhesive layer 41.SELECTED DRAWING: Figure 2 【課題】表示装置の性能を向上させる技術を提供する。【解決手段】第１前面、および第１前面の反対側にある第１背面を備えている基板１０と、第１前面と対向する第２背面、および第２背面の反対側にある第２前面を備えている基板２０と、基板１０の第１前面と基板２０の第２背面との間に配置される液晶層ＬＱＬと、基板２０の第２前面上に接着層４１を介して接着固定された導光板４０と、導光板４０の第１側面と対向する位置に配置された光源部５０と、を有し、導光板４０の屈折率は、接着層４１の屈折率よりも低い、表示装置を用いる。【選択図】図２
