To provide a display device in which the decrease in SN ratio is suppressed.SOLUTION: A display device includes a display panel, a plurality of light-receiving elements that receive light and exist inside a display region of the display panel when viewed from a normal direction of the display panel, and a light guide unit that is provided overlapping with the light-receiving element. The light guide unit includes a light guide path at least a part of which overlaps with the light-receiving element, and a light-blocking part whose light absorption ratio is higher than that of the light guide path. The light guide path is inclined in a predetermined first direction with respect to the normal direction of the display panel.SELECTED DRAWING: Figure 10 【課題】ＳＮ比の低下を抑制する表示装置を提供する。【解決手段】表示装置は、表示パネルと、表示パネルの法線方向からみて、表示パネルの表示領域の内側にある、光を受光する複数の受光素子と、受光素子と重畳して設けられる導光部と、を備える。導光部は、受光素子に少なくとも一部が重畳する導光路、及び、導光路よりも光の吸収率が高い遮光部を含む。導光路は、表示パネルの法線方向に対して、所定の第１方向に傾斜している。【選択図】図１０
