Document Type and Number:
Japanese Patent JP6586635
Kind Code:
B2
Abstract:
An image display device includes a light source, a scanner, a screen, a virtual image optical system and a screen incident angle correcting optical system. The light source emits laser light. The scanner scans the laser light. An image is formed on the screen by the scanned laser light. The virtual image optical system generates a virtual image of the image by the laser light having transmitted through the screen. The screen incident angle correcting optical system orients the scanned laser light toward the screen. The scanner performs at least first scanning and second scanning that has a scanning direction different from a scanning direction of the first scanning. The screen includes a lenticular lens having a lens pitch in a direction parallel to the first scanning. The lens pitch of the lenticular lens is larger than a beam diameter of the laser light near a light receiving surface of the screen.
