Backlight module and liquid crystal display with the same

A liquid crystal display, comprising:

• a backlight module comprising:
• a backboard;
• a light guide plate, arranged on the backboard;
• an optical film, arranged on the light guide plate;
• a frame, fixed with the backboard and configured to fix the light guide plate and the optical film, wherein an inner lateral side of the frame comprises a groove and a lateral side of the optical film is accommodated in the groove such that an upper surface and a lower surface of the optical film substantially contact the groove;
• and
• an inclined block, arranged on an upper surface of the frame;
• wherein a first slant of the inclined block is smoothly connected to the upper surface of the frame;
• and
• a liquid crystal panel comprising:
• an upper display substrate;
• a lower display substrate, arranged with the upper display substrate;
• an upper polarizer, arranged on an upper surface of the upper display substrate;
• and
• a lower polarizer, arranged on a lower surface of the lower display substrate and the upper surface of the frame, wherein a second slant is formed at a junction of the lower surface of the lower polarizer and a lateral surface of the lower polarizer, and the second slant and the first slant fit correspondingly.
