Document Type and Number:
Japanese Patent JP7479999
Kind Code:
B2
Abstract:
An image projector is provided for which assembly work and optical axis adjustment are easy while visibility at both sides of an image is secured. This image projector includes a lighting substrate (25), a lens part (23) that adjusts an optical axis of emitted light from light-emitting elements (25a), and an image display part (22) which displays an image on a display surface and through which the emitted light is transmitted. The display surface of the image display part (22) has a central region (22a) and side regions (22b) located on both sides. In the lens part (23), a first lens region (23b) corresponding to the central region (22a) and second lens regions (23c) corresponding to the side regions (22b) are integrally formed. Radiation directions of light having passed through the second lens regions (23c) are more inclined toward laterally outer sides than a radiation direction of light having passed through the first lens region (23b).
