| description | To provide a display device and a projection device that suppress a display element from rising in temperature.SOLUTION: There is provided a display device (3) comprising: a first reflection type display element (57) and a second reflection type display element (55) which each comprise a light source part (10) and a light modulation part (103); a light separation synthesis member (53) which separates light from the light source part (10) into first light and second light, emits the first light toward the first reflection type display element (57) and the second light to the second reflection type display element (55), and puts together the first light after modulation reflected by the first reflection type display element (57) and the second light after modulation reflected by the second reflection type display element (55); and a light absorption member (61) which covers a part of the first reflection type display element (57) except the light modulation part (103), and absorbs the second light after modulation reflected by the second reflection type display element (55) to travel toward the first reflection type display element (57). There is also provided a projection device (1) which comprises the display device (3).SELECTED DRAWING: Figure 1
【課題】表示素子の温度上昇を抑制する表示装置および投写装置を提供する。【解決手段】光源部（１０）と、光変調部（１０３）をそれぞれ備える、第１反射型表示素子（５７）および第２反射型表示素子（５５）と、光源部（１０）からの光を第１の光と第２の光とに分離して、第１の光は第１反射型表示素子（５７）に向けて、第２の光は第２反射型表示素子（５５）に向けてそれぞれ出射し、第１反射型表示素子（５７）によって反射された変調後の第１の光と第２反射型表示素子（５５）によって反射された変調後の第２の光とを合成する光分離合成部材（５３）と、第１反射型表示素子（５７）における光変調部（１０３）を除く一部分を覆い、第２反射型表示素子（５５）に反射されて第１反射型表示素子（５７）に向かう変調後の第２の光を吸収する光吸収部材（６１）と、を備える、表示装置（３）、および表示装置（３）を備える投写装置（１）である。【選択図】図１ |
