An image display panel includes: an image display unit including pixels arranged in horizontal and vertical directions, and displaying a composite image including different images; and an image separating unit facing the image display unit, and separating the composite image into the different images using light-transmitting portions transmitting light and light-shielding portions shielding the light. Each of the pixels includes sub-pixels each including a light emitting region, the sub-pixels have sizes different from sizes obtained by equally dividing the pixel, the light-transmitting portions are open in a diagonal direction, and each of boundary lines between the light-transmitting portions and the light-shielding portions is determined by moving parallel a continuous line that connects lines each connecting gravity centers of adjacent sub-pixels or adjacent light emitting regions in the sub-pixels, or to be a continuous line that connects lines each connecting midpoints of the gravity centers.
