Abstract
A door () includes a tabular main body (), a liquid crystal device () which is disposed in an aperture portion formed in the main body (), a handheld portion (A) which is attached to the main body (), and a touch sensor () which is attached to the handheld portion (A). Because the touch sensor () is attached to the handheld portion (A), when a person's hand touches the handheld portion (A), the touch sensor () senses the person's hand. The liquid crystal device () is capable of varying between an invisible state and a visible state reversibly, and is made into a visible state in the case where the touch sensor () senses a person's hand.
