A light source unit is provided with: a display device which has a plurality of pixels and is capable of displaying an image; a color changing sheet on which light emitted from the display device is incident; an imaging optical system; and a driving unit that changes a positional relationship between the display device and the color changing sheet. The imaging optical system forms a first image corresponding to the image. The color changing sheet has: a first region in which light is incident from the pixels and light of a first color is emitted; and a second region in which light is incident from the pixel and light of a second color is emitted. The driving unit changes a positional relationship between the display device and the color changing sheet between a first positional relationship in which light emitted from one of the pixels is incident on the first region and a second positional relationship in which light emitted from the one of the pixels is incident on the second region.
光源单元具备:显示装置,其具有多个像素,能够显示图像;颜色变化片材,其入射从所述显示装置出射的光;成像光学系统;驱动单元,其使所述显示装置与所述颜色变化片材的位置关系变化。所述成像光学系统形成与所述图像对应的第一像。所述颜色变化片材具有:从所述像素入射光,并出射第一色的光的第一区域;从所述像素入射光,并出射第二色的光的第二区域。所述驱动单元使所述显示装置与所述颜色变化片材的位置关系在使从一个所述像素出射的光向所述第一区域入射的第一位置关系和使从所述一个像素出射的光向所述第二区域入射的第二位置关系之间变化。
