PROBLEM TO BE SOLVED: To provide an on-vehicle image display device capable of always sufficiently and visually recognizing a display image without artificial operation even if a sunshine direction is varied when the vehicle is traveled while displaying a road map and the other images at a time zone of daytime. SOLUTION: The on-vehicle image display device is provided with a display panel 2 having a display surface d light-emitted by feeding of power and attitude-adjustably arranged at a predetermined position in the vehicle; a brightness adjustment part 1D for adjusting light emission brightness of the display surface d; an angle adjustment mechanism 3 for adjusting the attitude of the display panel 2 and its drive source 4; a GPS receiving part 11 for receiving transmission data from GPS satellite; a detection part 12 for detecting an inclination angle in a longitudinal direction relative to a horizontal surface of the vehicle; an operation part 1B for calculating the sunshine direction relative to an advancement direction of the vehicle based on the receiving data by the GPS receiving part 11 and the inclination angle data of the vehicle detected by the detection part 12; and a control part 1A for controlling the brightness adjustment part 1D and the drive source 4 based on the sunshine direction calculated by the operation part 1B.
