ABSTRACT:
In a display device, a backlight unit emits light forward. Picture elements are arranged in columns and rows to define a picture element plane and each of the picture elements has a transmitting region to transmit light coming from the backlight unit. Collecting elements are arranged in front of the backlight unit to transmit and collect the light on the picture element plane. Each collecting element is associated with the transmitting region of one of the picture elements. The light transmitted through each collecting element forms a beam spot on the picture element plane. The center of the beam spot is located within the transmitting region associated with the collecting element. Two beam spots, formed on two picture elements that are adjacent to each other in a row direction, have their centers of mass shifted from each other in a column direction on the picture element plane.
