PROBLEM TO BE SOLVED: To provide a display in which light reflected by a transmission member is not condensed at a specific on point.SOLUTION: A display comprises an opening through which light beams forming an image to be displayed is emitted to the outside. The opening is provided with a transmission member through which the light beams pass; the transmission member has a concave surface on an emission surface side; when a symmetry axis when a parabola is drawn is defined as a reference axis of the concave surface, the shape of the concave surface is a non-circular-arc shape in which its curvature is reduced as being separated from the reference axis.SELECTED DRAWING: Figure 2

    【課題】透過部材により反射された光が特定の一点に集光しない表示装置を提供する。【解決手段】表示する像を形成する光束を外部へ射出する開口部を備える表示装置であって、前記開口部には、前記光束が透過する透過部材が設けられ、前記透過部材の射出面側は凹面であり、放物線を描いた際の対称軸を前記凹面の基準軸と定義すると、前記凹面の形状は、この放物線よりも、前記基準軸から離れるほど曲率が緩くなる非円弧形状である、表示装置。【選択図】図2
