Backlight module

A backlight module, comprising:

• a light guide plate having a light incident surface;
• a light source module disposed adjacent to the light incident surface and having at least one light-emitting element, wherein a light beam emitted by the light-emitting element is capable of entering the light guide plate through the light incident surface;
• a first catch member engaging with a first end of the light source module, wherein the first catch member has an extension part extending towards the light incident surface of the light guide plate, and the extension part of the first catch member has an end surface being disposed beside and facing the light incident surface;
• a second catch member pressing against a second end of the light source module, wherein the second catch member has an extension part extending towards the light incident surface of the light guide plate, and the extension part of the second catch member has an end surface being disposed beside and facing the light incident surface;
• a cushion member disposed between the light incident surface of the light guide plate and the light source module and touching the end surface of the extension part of the first catch member and the end surface of the extension part of the second catch member, wherein the cushion member is between the end surface of the extension part of the first catch member and the light incident surface and between the end surface of the extension part of the second catch member and the light incident surface, so that the end surface of the extension part of the first catch member and the end surface of the extension part of the second catch member are capable of being against the light incident surface of the light guide plate through the cushion member;
• and
• at least one fastening member capable of fastening the first catch member, the second catch member, and the light source module together.
