PROBLEM TO BE SOLVED: To provide a transmission type screen and a display device that can improve visibility of projection video.SOLUTION: A transmission type screen (1) has a plurality of recessed parts (11) and a flat part (12), where the recessed parts (11) are not formed, formed on an incidence plane (1a). Each recessed part (11) has a plane (11a) which refracts incident light so as to make an angle γ between emission light and an emission surface (1b) larger than an angle(α) between the incident light and flat part (12), and a plane (11b) which guides the incident light into the transmission type screen (1).SELECTED DRAWING: Figure 3 |
