VIRTUAL IMAGE DISPLAY DEVICE

摘要

A light guide member which guides video light includes a peripheral area forming portion extending to the outside of an effective light flux guide portion which is an area through which an effective light flux of the video light passes, and thus for example, even when ghost light resulting from components generated by unintended reflection or scattering in a position such as a side surface forming portion of the light guide member may be generated, the side surface forming portion can be separated from the effective light flux guide portion.

主权项
