According to one embodiment, a display device (100) includes a display unit (110), a first optical element (210), and a reflector (130). The display unit (110) includes a first pixel (1210) emitting a first light, and a second pixel (1110) emitting a second light. The first optical element (210) has an incident surface (21) and an emission surface (22). A diameter of a bundle of rays of the first light at the incident surface (21) is a first value. A diameter of a bundle of rays of the second light at the incident surface (21) is a second value. A diameter of the bundle of rays of the first light at the emission surface (22) is a third value. A diameter of the bundle of rays of the second light at the emission surface (22) is a fourth value. A ratio of the third value to the first value is different from a ratio of the fourth value to the second value. |
