Backlight module and liquid crystal display

A backlight module, comprising at least one light source, an optical film and a reflection plate being parallel to each other, there fanning a light guide region between the optical film and the reflection plate, the length of the light guide region being equal to that of one having the longer length of the optical film and the reflection plate, wherein:

• the backlight module also comprising a curved reflection sheet, one end of the curved reflection sheet extending into the light guide region along a length direction of the optical film and being connected to the reflection plate, and the other end of the curved reflection sheet and the optical film being respectively located at two opposite sides of the light source;
• the light source including a light-emitting surface, the light-emitting surface facing the curved reflection sheet and the reflection plate, all the lights emitted by the light source being projected to the curved reflection sheet and the reflection plate, and then being reflected by the curved reflection sheet and the reflection plate to enter into the optical film.

A liquid crystal display, wherein, the liquid crystal display comprising a backlight module, the backlight module comprising at least one light source, an optical film and a reflection plate being parallel to each other, there forming a light guide region between the optical film and the reflection plate, the length of the light guide region being equal to that of one having the longer length of the optical film and the reflection plate;

• the backlight module also comprising a curved reflection sheet, one end of the curved reflection sheet extending into the light guide region along a length direction of the optical film and being connected to the reflection plate, and the other end of the curved reflection sheet and the optical film being respectively located at two opposite sides of the light source;
• the light source including a light-emitting surface, the light-emitting surface facing the curved reflection sheet and the reflection plate, all the lights emitted by the light source being projected to the curved reflection sheet and the reflection plate, and then being reflected by the curved reflection sheet and the reflection plate to enter into the optical film.
