A display device includes a display module and a color calibrator. The display module includes a first casing and a circuit board. The first casing has a positioning recess and an accommodating recess. The circuit board has a first electrical connecting portion. The circuit board is disposed corresponding to the positioning recess and the first electrical connecting portion is exposed from the positioning recess. The color calibrator includes a second casing, a second electrical connecting portion and a sensor. The second casing has a protruding portion. The color calibrator is selectively accommodated in the accommodating recess or connected to the positioning recess by the protruding portion. When the protruding portion of the color calibrator is connected to the positioning recess, the first electrical connecting portion is electrically connected to the second electrical connecting portion and the sensor faces a display area of the display module.

A motion detecting section 30 detects the attitude of a head-mounted display device worn on the head of a user. A visual line direction determining section 32 determines a visual line direction in accordance with the detected attitude of the head-mounted display device. An image generating section 34 generates an image based on the determined visual line direction. An image providing section 36 provides the head-mounted display device with the generated image. An instruction acquiring section 24 acquires from an input device 6 an instruction to switch the visual line direction. When the instruction acquiring section 24 acquires the switching instruction, the visual line direction determining section 32 changes the visual line direction by a predetermined angle.

A display apparatus that comprises a display screen and a set of support portions, is provided. The display apparatus receives a user input that corresponds to a configuration of the display screen and controls motion of the set of support portions based on the received user input. A change in a surface curvature of the display screen is based on the motion of the set of support portions.

A head mounted display is worn on a head of a user. The head mounted display includes a display device configured to display image; a casing that houses the display device; a right-eye lens and a left-eye lens attached to the casing; and an inter-lens structure disposed between the right-eye lens and the left-eye lens. The head mounted display causes the user to recognize a color of at least a part of the inter-lens structure as a color that is equal to or brighter than a skin color when the user wears the head mounted display.
