A reflective element includes multiple reflective cavities and multiple spacers. Each reflective cavity has an upper opening, a lower opening, and a peripheral surface. A peripheral-surface bottom edge of the peripheral surface is disposed on a substrate of a light board, and the lower opening of the reflective cavity corresponds to one light emitting component. Each spacer includes a bottom surface, a first inclined surface, and a second inclined surface. The bottom surface is connected to the first inclined surface and the second inclined surface, and the bottom surface is disposed on the substrate and flush with the peripheral-surface bottom edge. The first inclined surface and the second inclined surface respectively serve as the side surfaces of adjacent two of the reflective cavities, and some of the spacers have a height difference between a top edge of the first inclined surface and a top edge of the second inclined surface.

Reflective element and backlight module

A backlight module includes a reflective plate, a plurality of light-emitting elements and a plurality of light guide plates. The reflective plate has light source grooves and first position limiting parts, and each light source groove has a reflective surface, a light outlet and a bottom side. The reflective surface is located between the light outlet and the bottom side. The first position limiting parts are respectively connected to the reflective surfaces and are respectively close to the light outlets. The light-emitting elements are respectively disposed in the light source grooves and respectively surrounded by the reflective surfaces. The light guide plates are respectively disposed in the light source grooves and respectively located between the reflective surfaces and the light-emitting elements. The first position limiting parts are respectively adapted to block the light guide plates from being separated from the reflective plate from the light outlets.

Backlight module

A tray includes a bottom plate, a surrounding wall, and limit blocks. The surrounding wall surrounds a periphery of the bottom plate. A plurality of protrusions are arranged on an inner side of the surrounding wall. The limit blocks are separably assembled on the bottom plate. Each of the limit blocks has a limit groove and a limit portion. The limit groove is adapted to be clamped with one of the protrusions. The limit portion is positioned on an opposite side of the limit groove. In this way, the tray may correspond to plates of different sizes via the limit blocks.
