摘要： A backlight module includes a light source, a light guide plate and a light-adjusting member. A light source chromaticity is measured from light generated by the light source. The light guide plate has a light-incident surface and a light-emitting surface. Light generated by the light source enters the light guide plate and emits out from the light-emitting surface. With the light-adjusting member, a first light guide plate chromaticity is measured from the light-emitting surface. There is a first difference value between the first light guide plate chromaticity and the light source chromaticity. Without the light-adjusting member, a second light guide plate chromaticity is measured from the light-emitting surface. There is a second difference value between the second light guide plate chromaticity and the light source chromaticity. The first difference value is different from the second difference value.

摘要： A light-emitting device is provided, and includes a light guide plate and a light source. The light guide plate includes a main body, in which the main body has a light-incident surface. The light source is disposed adjacent to the light-incident surface. The light-emitting device is selectively disposed in different arrangements. When the light-emitting device is disposed in a first arrangement, the light-emitting device is able to provide a first light-emitting function towards a first direction and to provide a second light-emitting function towards a second direction. When the light-emitting device is disposed in a second arrangement, the second light-emitting function towards the second direction is changed, and the first light-emitting function towards the first direction is also changed.

摘要： A light guide plate, a backlight module and a display device are provided. The light guide plate includes a main body, first stripe microstructures, second stripe microstructures and third stripe microstructures. The main body includes a light incidence surface and an optic surface having a first area and a second area. The first area is disposed nearer the light incidence surface. The first stripe microstructures and the second stripe microstructures are respectively disposed on the first area and the second area. Each of the first stripe microstructures and the second stripe microstructures extends along the direction vertical to the light incidence surface. A width of one end of each second stripe microstructure near the light incidence surface is smaller than a width of the other end away from the light incidence surface. The third stripe microstructures are distributed on a partial or the whole region of the optic surface.
