| description | A light source module and a display device are provided. The light source module includes a light-emitting element, a light-guiding plate, and a filter. The light-emitting element includes a light-emitting surface. The light-guiding plate includes a light-incident surface, and the light guide plate is disposed such that the light-incident surface faces the light-emitting surface. The filter is disposed between the light-emitting surface and the light-incident surface, and a center wavelength of a reflection band of the filter falls in a range of 570 nm to 590 nm. The light-emitting element emits a first light having a first color temperature from the light-emitting surface. The first light is filtered into the second light having a second color temperature after it passes through the filter. The light-incident surface of the light-guiding plate receives the second light. The first color temperature is lower than the second color temperature. |
