A light emitting element (1) includes: a plurality of light emitting diodes [3 (R1, G11, ...)] of two or more colors; and a light guide plate (4) for causing light from the respective plurality of light emitting diodes [3 (R1, G11, ...)] to surface-emit. The light emitting diodes are provided along the light guide plate (4) in a given order. The light guide plate (4) includes: a color mixing section (5) for mixing colors of light from the respective plurality of light emitting diodes [3 (R1, G11, ...)]; and a display section (6) for causing the light, which has been subjected to a color mixture by the color mixing section (5), to surface-emit. The plurality of light emitting diodes [3 (R1, G11, ...)] decrease in their respective luminous intensities from a center toward ends of the light guide plate (4). This allows obtaining a well color-mixed white light source without being colored in a color of light emitted from a light emitting diode provided on a side end surface side of a light guide plate.
