摘要： A liquid crystal shutter eyeglass that can solve the problem in which the provision of excellent images cannot be kept if the situation of the viewer varies is provided. A liquid crystal shutter (2) has a light transmitting and shading region in which a state can change between a light transmitting state in which light is caused to transmit and a light shading state in which light is caused to be shaded. A driving section (51) changes the state between the light transmitting state and the light shading state of a driving region that is at least part of the light transmitting and shading region. A controlling means (52) adjusts at least one of a size and a position of the driving region of which the driving section (51) changes the state.
