Abstract
A pair of shutter glasses capable of reducing decrease in brightness of displayed images to be visually recognized is provided. A pair of shutter glasses include a pair of light selectors the state of each of which is switched between a light transmitting state in which the light selector transmits light and a light blocking state in which the light selector blocks light. When a full area where light is transmitted or blocked in the light transmitting state or the light blocking state is virtually divided into a plurality of divided areas along a first direction, each of the light selectors switches the state of each of the plurality of divided areas between the light transmitting state and the light blocking state sequentially along the first direction.
