Abstract

Disclosed is an electronic device implementing a pin mirror-type display to address a double image problem, the electronic device including: a plate-shaped optical element forming an inner side surface directed toward a user's eyes and an outer side surface opposite to the inner side surface; an optical driving assembly allowing image light to be incident on one side in a lengthwise direction of the optical element; a reflection member provided on the other side in the lengthwise direction of the optical element so that the incident image light travels along an inside of the optical element; and a pin mirror member reflecting the reflected image light toward the reflection member to make a depth of field (DOF) deep, and disposed between a point at which the image light is incident from the optical element and a point at which the image light is reflected in the reflection member.
