摘要： A light guide for a virtual image device to guide and emit image light output from an image display element to display a virtual image. The light guide includes a light-guide member and an optical member. The light-guide member includes an incidence portion to receive the image light and an exit portion to emit the image light to an outside, and a reflective portion inclined relative to the incidence portion to guide the image light received by the incidence portion into the light guide. The light-guide member also includes an extraction portion including first planes each inclined relative to the exit portion and second planes each parallel with the exit portion, to guide the image light from each first plane to the exit portion and extract the image light. The optical member includes a parallel plane and an inclined portion.
