Abstract
A light emitting device includes an LED chip to emit light, and a light emitting element holding member that includes a base on which the LED chip is disposed and a wall standing from the base such that the wall has an inner surface that faces the LED chip. The wall includes inner surfaces that are formed in black, and inner surfaces that are formed in white. The inner surfaces that are formed in black mutually oppose each other. The inner surfaces that are formed in white mutually oppose each other in a direction orthogonal to the direction in which the inner surfaces that are formed in black mutually oppose each other.
Claims9
A light emitting device comprising:
- at least one light emitting element to emit light;
- and
- a light emitting element holding member that includes a base on which the light emitting element is disposed and a wall standing from the base such that the wall has an inner surface that faces the light emitting element, wherein the inner surface of the wall includes a first area extending from the base to an opposite terminal edge of the inner surface that is formed in a dark color, and a second area extending from the base to an opposite terminal edge of the inner surface having a reflectance that is greater than that of the first area with respect to the light emitted by the light emitting element,
- wherein the wall stands from the base such that the wall includes an inner circumferential surface entirely surrounding the light emitting element disposed on the base, the first area defined by two areas mutually opposing each other within the inner circumferential surface of the wall, and the second area being defined by two areas that each separate the two first areas and are mutually opposing each other in a direction intersecting with a direction in which the two areas of the first area mutually oppose each other within the inner circumferential surface of the wall.
A display unit comprising:
- light emitting devices;
- and
- a circuit substrate on which the light emitting devices are arranged in a matrix,
- wherein the light emitting devices each comprise:
- at least one light emitting element to emit light;
- and
- a light emitting element holding member that includes a base on which the light emitting element is disposed and a wall standing from the base such that the wall has an inner surface that faces the light emitting element wherein the inner surface of the wall includes a first area extending from the base to an opposite terminal edge of the inner surface that is formed in a dark color, and a second area extending from the base to an opposite terminal edge of the inner surface having a reflectance that is greater than that of the first area with respect to the light emitted by the light emitting element,
- wherein the wall stands from the base such that the wall includes an inner circumferential surface entirely surrounding the light emitting element disposed on the base, the first area defined by two areas mutually opposing each other within the inner circumferential surface of the wall, and the second area being defined by two areas that each separate the two first areas and are mutually opposing each other in a direction intersecting with a direction in which the two areas of the first area mutually oppose each other within the inner circumferential surface of the wall.
