METHOD FOR DISPLAYING IMAGE, IMAGE DISPLAY PANEL, AND IMAGE DISPLAY DEVICE

1 . A method for displaying an image using (i) an image display unit that includes a plurality of pixels arranged in a horizontal direction and a vertical direction and displays a composite image including a plurality of different images and (ii) an image separating unit that faces the image display unit and separates the composite image displayed on the image display unit into the different images using light-transmitting portions that transmit light and light-shielding portions that shield the light, the light-transmitting portions and the light-shielding portions being alternately arranged in the horizontal direction,

wherein each of the pixels includes a plurality of sub-pixels each including a light emitting region,

the sub-pixels in each of the pixels have sizes different from sizes obtained by equally dividing the pixel,

the light-transmitting portions are open in a diagonal direction with respect to the vertical direction, and

each of boundary lines between the light-transmitting portions and the light-shielding portions is determined (i) by moving parallel a continuous line that connects lines each of which connects gravity centers of adjacent sub-pixels or adjacent light emitting regions that are included in the sub-pixels or (ii) to be a continuous line that connects lines each of which connects midpoints of the gravity centers of the adjacent sub-pixels or the adjacent light emitting regions.
