    摘要： The display apparatus of the present invention includes a plurality of condensing elements 54a provided between a lighting device and a display panel 100. A first substrate 10 of the display panel 100 is placed on the side of a display medium layer 23 facing the lighting device while the second substrate 11 is placed on the observer side thereof. Each pixel element Px has a transmission region Tr for display in the transmission mode using light 41 incident from the lighting device, and the first substrate 10 has a transparent electrode region defining the transmission region Tr on the side facing the display medium layer 23. Each condensing element 54a is placed to correspond to the transmission region Tr of the pixel element Px so as to form the converging point of light outputted from the lighting device at a position closer to the observer with respect to the display medium layer 23. The present invention improves the use efficiency of light from the lighting device and enhances the luminance without constraints of arrangement of pixel elements and the like.

    摘要： 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.
