PROBLEM TO BE SOLVED: To provide a display device that can display a bright picture without reducing a MTF.SOLUTION: A light guide plate 3 to which light emitted from a light source 2 is made incident emits light from a light emission plane 32. A prism sheet 5 reflects light of a predetermined angle of the light emitted from the light emission plane 32, causes the light to be made incident to the light guide plate 3 and transmits light of other angle. A polarization control element 8 is provided in parallel with the light emission plane 32 between a 1/4 wavelength plate 12 and a reflection type liquid crystal display element 1. The polarization control element 8 separates light emitted from the 1/4 wavelength plate 12 into a first polarization causing the light to be transmitted as illumination light to be made incident to the reflection type liquid crystal display element 1 and a second polarization causing the light to be reflected so as to be made incident to the light guide plate 3, and causes light modulated by the reflection type liquid crystal display element 1 and emitted to be reflected so as to move toward an imaging lens 10. The imaging lens 10 emits incident light toward a combiner 21. |
