Abstract:
The present application discloses OEL display panel including OEL board including organic emission elements situated in respective emission regions compartmentalized by confining wall, and black matrix facing OEL board. The black matrix is provided with openings, each of which allows passage of light from each of the organic emission elements. Organic emission elements include first organic emission element with organic emission layer for emitting light in first emission color, and second organic emission element with organic emission layer for emitting light in second emission color different from first emission color. Openings include first opening corresponding to first organic emission element, and second opening corresponding to second organic emission element. First organic emission element has lower emission efficiency than second organic emission element does. Thermal conductivity is higher around first opening than second opening.
