Abstract: Condition 1 (an absolute value of a difference between IB×B and EB×B is 55% or smaller) and condition 2 (an absolute value of a difference between IY×Y and EY×Y is 55% or smaller) are satisfied, where, when an area of the light-emitting surface is equally divided into inner and outer regions by a boundary line as an outer edge of a region similar in shape to the light-emitting surface in plan view of a white LED package, IB (%) is an area ratio of blue LED chips in the inner region; IY (%) is an area ratio of the region where no blue LED chips is disposed in the inner region; EB (%) is an area ratio of the blue LED chips in the outer region; and EY (%) is an area ratio of the region where no blue LED chip is disposed in the outer region.

Abstract: A backlight module and a display device. The backlight module includes: at least one substrate; a plurality of light-emitting devices configured on the at least one substrate and configured in a matrix shape at intersections of orthogonal virtual lines, and having: a light-emitting element configured for emitting a first color light; a light-transmitting member configured for converting the first color light into a second color light; a beam control component configured for diffusing and emitting the second color light; a reflection member configured at least among the plurality of light-emitting devices; a light-diffusing member configured on a light-emitting side of the light-emitting devices; wherein a surface of the reflection member facing the light-diffusing member has colored areas AA that render an optical complementary color of a first color, and each of the colored areas AA is located at least at a gravity center of an area enclosed by four adjacent light-emitting devices.

Abstract: Provided is light flux controlling member for controlling a distribution of light emitted from a plurality of light emitting elements disposed on a substrate, which includes a plurality of incidence units for allowing incidence of the light emitted from the plurality of light emitting elements, respectively; and an emission unit which emits the light incident on the plurality of incidence units while guiding the light, and which is disposed between the plurality of incidence units in a direction along the substrate. The light flux controlling member has a rectangular shape with rounded corners in plan view, and includes four corner portions and four side portions, and the inclination angle of the corner portions is different from the inclination angle of the side portions.

Abstract: A light flux controlling member includes a plurality of incidence units and a plurality of emission units. When light is entered into the light flux controlling member from a side surface of one emission unit of the plurality of emission units, an integrated value of an illuminance on a virtual line in a first region is greater than an integrated value of an illuminance on the virtual line in a second region on a virtual plane disposed immediately above the light flux controlling member and having a plan shape identical to that of the light flux controlling member, the virtual line passing through a first point located immediately above a center of gravity of the light flux controlling member and a second point located immediately above a center of the side surface on the virtual plane.
