To provide: a translucent resin sheet allowing projection of an outgoing beam emitted from a projection display onto a screen with a color tone as designed even when attached in a curved state as a translucent cover member that transmits the outgoing beam; and a projection display and a movable body that comprise the translucent resin sheet and have excellent reliability.SOLUTION: A translucent resin sheet is used as a translucent cover member that transmits an outgoing beam emitted from a projection display, and includes: a resin layer 3 comprising a resin material as a main material; and a hard coat layer 5 laminated on at least one face (top face) of the resin layer 3. A thickness direction phase difference (Rth) at a measurement wavelength of 543 nm is 145 nm or less. A relational expression (1), Re440-Re660<40 nm, is satisfied, where Re440 [nm] refers to a phase difference at a measurement wavelength of 440 nm, and Re660 [nm] refers to a phase difference at a measurement wavelength of 660 nm.SELECTED DRAWING: Figure 3
【課題】投射型表示器から出射される出射光を透過させる透過性カバー部材として湾曲状態で装着されたとしても、スクリーンに出射光を設計通りの色調で投影することができる透光性樹脂シート、かかる透光性樹脂シートを備える信頼性に優れた投射型表示器および移動体を提供すること。【解決手段】透光性樹脂シートは、投射型表示器から出射される出射光を透過させる透光性カバー部材に用いられ、樹脂材料を主材料として構成された樹脂層3と、この樹脂層3の少なくとも一方の面(上面)に積層されたハードコート層5とを有し、測定波長543nmにおける厚み方向位相差(Rth)が145nm以下であり、かつ、測定波長440nmにおける位相差をRe440[nm]とし、測定波長660nmにおける位相差をRe660[nm]としたとき、下記関係式(1)を満足する。Re440−Re660<40nm ・・・ (1)【選択図】図3
