| description | To provide a display device that can reduce thickness and improve display characteristics, and a head-mounted display including the display device.SOLUTION: A display device (100) comprises: a display panel (10), a linearly polarizing plate (20) and a first polarized light-selective reflecting plate (31) provided sequentially toward an observer side; a first phase difference plate (41) and a first lens (51); a half mirror (60); a second lens (52) and a second phase difference plate (42) provided closer to an observer side of the half mirror and arranged to face each other; and a second polarized light-selective reflecting plate (32). The first lens and the second lens have asymmetric shapes with respect to the half mirror as a plane of symmetry in a cross-sectional view along a direction from the display panel toward the second polarized light-selective reflecting plate.SELECTED DRAWING: Figure 1
【課題】薄型化が可能あり、かつ、表示特性を向上させることができる表示装置、及び、該表示装置を備えたヘッドマウントディスプレイを提供する。【解決手段】観察者側に向かって順に設けられた表示パネル（１０）、直線偏光板（２０）、第１の偏光選択反射板（３１）、第１の位相差板（４１）及び第１のレンズ（５１）と、ハーフミラー（６０）と、上記ハーフミラーの観察者側に設けられ、かつ、互いに対向して配置された第２のレンズ（５２）及び第２の位相差板（４２）と、第２の偏光選択反射板（３２）と、を備え、上記表示パネルから上記第２の偏光選択反射板に向かう方向に沿った断面視において、上記第１のレンズと上記第２のレンズとは、上記ハーフミラーを対称面として非対称な形状を有する、表示装置（１００）。【選択図】図１ |
