An image display device, comprising:
- a light projecting unit comprising a plurality of light emitting elements;
- a display panel which is located so as to receive light from the light projecting unit and is configured so as to display a plurality of frames;
- a barrier panel configured so as to overlap the display panel and include a plurality of light transmitting portions and a plurality of dimming portions;
- and
- a controller configured so as to control the light projecting unit, the display panel, and the barrier panel,
- a traveling direction of at least part of image light emitted from the display panel being divided for a right eye and a left eye of a user, by the plurality of light transmitting portions and the plurality of dimming portions,
- the display panel being configured so as to include a first display region, and
- to display a right-eye image which is viewed by the right eye of the user, in a right-eye visible region of the first display region, and a left-eye image which is viewed by the left eye of the user, in a left-eye visible region of the first display region,
- the barrier panel being configured so as to include a first barrier region corresponding to the first display region, and
- configured so that the plurality of light transmitting portions and the plurality of dimming portions are formed in the first barrier region so that the right-eye visible region and the left-eye visible region are at different positions of the first display region,
- the light projecting unit being configured so as to include a first light emitting region corresponding to the first display region,
- the controller being configured so that, in a case where two consecutive frames are displayed, a portion located in the first display region is displayed as one parallax image frame including a first subframe and a second subframe,
- configured so as to control, for each parallax image frame, display of a parallax image in the first display region and formation of the plurality of light transmitting portions and the plurality of dimming portions in the first barrier region so that an image displayed in each of the first subframe and the second subframe included in the one parallax image frame is combined and viewed as one parallax image by the user, and
- configured so that a light quantity of light emitted from the first light emitting region is reduced during a frame change period which includes a timing of changing display from the parallax image frame to a new parallax image frame.
