Claim:
1. A display apparatus comprising: a detector configured to detect one or more user viewing positions; a display configured to have a changeable curvature; and a controller configured to receive information of the one or more user viewing positions from the detector, determine deviations between right-side viewing angles and left-side viewing angles at each of the one or more detected user viewing positions for a first curvature and a second curvature of the display, and set the changeable curvature of the display based on the determined deviations between the right-side viewing angles and the left-side viewing angles, each of the right-side viewing angles is an angle formed by a sight line direction from the viewing position at which a respective -user is positioned toward a right distal end of the display and a line positioned in a direction perpendicular to a tangent line of the right distal end of the display, and each of the left-side viewing angles is an angle formed by a sight line direction from the viewing position at which the respective user is positioned toward a left distal end of the display and a line positioned in a direction perpendicular to a tangent line of the left distal end of the display.
