To provide a virtual image display device and a reflection member which can reduce external light that is concentrated on a display unit without decreasing the brightness of the display and changing the hue when the sight line moves.SOLUTION: A virtual image display device comprises: a polarizing plate (150) which transmits one polarized light emitted from a display unit and one polarized light in external light toward the display unit; a liquid crystal layer (132) which is provided on a reflection surface side of a reflection type polarizing plate (131), performs polarization-rotation between the one polarized light and the other polarized light in a first region (1321) corresponding to a partial region (1211) of the display region and transmits the one polarized light in a second region (1322) corresponding to the other region (1212) other than the partial region; and a liquid crystal control unit (163) which controls polarization rotation in the first region and transmission of the one polarized light in the second region by controlling ON or OFF of the voltage application to the first region and the second region of the liquid crystal layer.SELECTED DRAWING: Figure 5

    【課題】表示の明るさの低下や視線移動時の色味の変化がなく、表示部に集光される外光を低減可能とする虚像表示装置および反射部材を提供する。【解決手段】虚像表示装置において、表示部から出射される一方の偏光、および表示部に向かう外光における一方の偏光を透過させる偏光板(150)と、反射型偏光板(131)の反射面側に設けられ、表示領域の一部の領域(1211)に対応する第1領域(1321)にて、一方の偏光と他方の偏光との間で偏光回転させると共に、全体の表示領域のうち、一部の領域以外の他の領域(1212)に対応する第2領域(1322)にて、一方の偏光を透過させる液晶層(132)と、液晶層の第1領域、および第2領域に対する電圧印加のオンあるいはオフを制御することで、第1領域における偏光回転、および第2領域における一方の偏光の透過を制御する液晶制御部(163)と、を備える。【選択図】図5
