LIGHT SOURCE FOR TESTING AND TESTING INSTRUMENT PROVIDED WITH SAME

摘要

A light source for testing (10) is provided with a planar light-emitting body (1) having a substrate (11), a first electrode (12), a second electrode (14) paired with the first electrode (12), and an organic light-emitting layer (13) disposed between the first electrode (12) and the second electrode (14). The organic light-emitting layer (13) has a plurality of light-emitting materials. The chromaticity of light irradiated by the planar light-emitting body (1) is included in an area formed by connecting, in an xy chromaticity diagram having MacAdam ellipses that have been magnified by a factor of 10, the centers of MacAdam ellipses having surface areas smaller than 5 × 10-4.
