Optical device, optical scanner, and image display device

摘要

An optical scanner is an optical device including a base portion that is rotatable about the Y-axis, a frame portion that is rotatable about the X-axis intersecting the Y-axis, and a shaft portion that supports the base portion so as to be rotatable about the Y-axis with respect to the frame portion. The optical scanner includes a light reflecting plate that is fixed to the base portion and includes a light reflecting portion with a light reflecting property. The frame portion is provided so as to surround the base portion. The shaft portion includes one end connected to the base portion and the other end connected to the frame portion. The light reflecting plate is separated from the shaft portion in the thickness direction of the light reflecting plate and overlaps the shaft portion, as viewed from the thickness direction.
