Provided is an image projection device capable of reducing the number of light-emitting surfaces of light-emitting elements required to suppress luminance unevenness while maintaining a high degree of design freedom even when a plurality of images are irradiated to different regions of a display unit. Comprises: an image display unit for displaying a projection image; a light irradiation unit that irradiates the image display unit with irradiation light; and an irradiation optical unit that irradiates irradiation light in the viewpoint direction via the display unit as a projection image, the projection image including a first image and a second image projected to different regions of the display unit, and the image display unit includes a first region (17b) in which the first image is displayed and a second region (17a) in which the second image is displayed. The light irradiation unit has first light source units (12b, 13b) that irradiate light to the first region (17b) and second light source units (12a, 13a) that irradiate light to the second region (17a), and the longitudinal direction of the first light source units (12b, 13b) and the longitudinal direction of the second light source units (12a, 13a) are arranged at an angle (theta).
提供向显示部的不同区域照射多个图像也能较高维持设计自由度,减少抑制亮度不均所需发光元件的发光面数的图像投影装置。包括:图像显示部,显示投影图像;光照射部,向图像显示部照射照射光;照射光学部,借助显示部向视点方向照射照射光作为投影图像,投影图像包含向显示部的不同区域投影的第一图像和第二图像,图像显示部具备显示第一图像的第一区域(17b)和显示第二图像的第二区域(17a),光照射部具有向第一区域(17b)照射光的第一光源部(12b、13b)及向第二区域(17a)照射光的第二光源部(12a、13a),第一光源部(12b、13b)的长边方向与第二光源部(12a、13a)的长边方向彼此以角度θ倾斜配置。
