PLANAR LIGHT-EMITTING DEVICE AND IMAGE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To achieve a planar light-emitting device outputting uniform planar light on the basis of light output from a plurality of point light sources.

SOLUTION: A planar light-emitting device 1 has light input windows 2a-2d for inputting light from point light sources 5a-5d disposed outside; and a light guiding member 3 having a scattering area 4 scattering the input light. Each window 2a-2d has a function of adjusting a light travelling direction and the like so that a light intensity distribution pattern in a free space has a symmetry of C4Vif necessary for the input light from the point light sources 5a-5d, and light scattering members are disposed so as to have the symmetry of C4Von the scattering area 4.
