The purpose of the present invention is to provide an image projection device which ensures visibility on both sides of an image and is easy to assemble and adjust an optical axis. An image projection device is provided with an illumination substrate (25), a lens unit (23) that adjusts the optical axis of light emitted from a light-emitting element (25a), and an image display unit (22) that displays an image on the display surface and transmits the emitted light, the display surface of the image display unit (22) having a central region (22a) and side regions (22b) located on both sides. A first lens region (23b) corresponding to the central region (22a) and a second lens region (23c) corresponding to the side region (22b) are integrally formed on the lens part (23), and the irradiation direction of light passing through the second lens region (23c) is inclined to the lateral outer side compared with the irradiation direction of light passing through the first lens region (23b).
本发明目的在于提供确保图像两侧的可见性并且组装作业和光轴调整容易的图像投影装置。本发明的图像投影装置具备照明基板(25)、对来自发光元件(25a)的出射光的光轴进行调整的透镜部(23)以及在显示面显示图像并透射出射光的图像显示部(22),图像显示部(22)的显示面具有中央区域(22a)和位于两侧的侧方区域(22b),透镜部(23)一体地形成有与中央区域(22a)对应的第1透镜区域(23b)和与侧方区域(22b)对应的第2透镜区域(23c),通过了第2透镜区域(23c)的光的照射方向相比于通过了第1透镜区域(23b)的光的照射方向,向侧方外侧倾斜。
