Patent ID: 10816884

Abstract:
A light emitting device has a columnar portion including a light emitting layer, and: (b−a)/L1>(d−c)/L2; a<b; c<d; and a<d, where a is the columnar portion's maximum width as viewed in a laminating direction, at a first position of the columnar portion closest to the substrate in the laminating direction, b is the columnar portion's maximum width, at a second position of the light emitting layer closest to the substrate, c is the columnar portion's maximum width, at a third position of the light emitting layer farthest from the substrate, d is the columnar portion's maximum width, at a fourth position of the columnar portion farthest from the substrate, and L1 is a distance between the first and second positions and L2 is a distance between the third and fourth positions.
