摘要： A planar light-emitting device allowing for high luminance uniformity has a plurality of light-emitting units (4), each including a lightguide plate (3) having a light-exiting surface, an opposite surface opposite to the light-exiting surface, a peripheral side surface extending between the respective peripheral edges of the light-exiting surface and the opposite surface, and a light-entrance surface (3a) defined by a part of the peripheral side surface. Each light-emitting unit further includes a light source (2) adjacently disposed to face the light-entrance surface to emit light into the lightguide plate through the light-entrance surface. The light-emitting units are arranged in a plurality of mutually adjacent rows with the light-exiting surfaces (3a) of their respective lightguide plates being substantially flush with each other. Adjacent rows of the light-emitting units are displaced relative to each other in the direction of the rows.

摘要： A single light guide plate illuminates both first and second liquid crystal display panels opposed to each other, the second liquid crystal display panel having a larger display area than that of the first liquid crystal display panel. A light-absorbing sheet is provided between the light guide plate and the first liquid crystal display panel to absorb light from the light guide plate and has a light-transmitting part aligned with the first liquid crystal display panel in a direction from the light guide plate toward the first liquid crystal display panel to transmit light from the light guide plate to the first liquid crystal display panel. A reflective polarizing sheet is provided between the second liquid crystal display panel and the light guide plate. The light-absorbing sheet eliminates brightness unevenness on the second liquid crystal display panel, which would otherwise occur due to the influence of the first liquid crystal display panel, and the reflective polarizing sheet allows effective utilization of light from the light guide plate.
