Abstract:
1. A pair of shutter glasses comprising: a first light selector and a second light selector, the state of each light selector 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, a full area of a surface of the first light selector and a full area of a surface of the second light selector are each virtually divided into a plurality of divided areas along a first direction, the first light selector and the second light selector switch 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, each of the plurality of divided areas extending in a second direction perpendicular to the first direction, and the first selector and the second light selector being arranged in the second direction, in a transition period in between periods where one light selector of the first light selector and the second light selector transitions from the light transmitting state to the light blocking state and an other light selector of the first light selector and the second light selector transitions from the light blocking state to the light transmitting state, a light blocking area in the one light selector sequentially increases in the first direction, while a light transmitting area in the other light selector sequentially increases in the first direction, the light transmitting area of the other light selector being disposed in an area of the light blocking portion of the one light selector in the first direction, the first light selector sequentially transitions a first boundary area in the first light selector to one of the light blocking state and the light transmitting state in the first direction, the first boundary area being a boundary between groups of the plurality of divided areas in the light blocking state and groups of the plurality of divided areas in the light transmitting state, the second light selector sequentially transitions a second boundary area in the second light selector to an other of the light blocking state and the light transmitting state in the first direction, the second boundary area being a boundary between groups of the plurality of divided areas in the light blocking state and groups of the plurality of divided areas in the light transmitting state, and the first boundary area and the second boundary area being located in different positions in the first direction.
