Liquid crystal display device and electronic equipment having the same

A liquid crystal display device with a backlight module comprising:

• a support frame including a bottom wall, and a main surrounding wall extending upwardly from and formed integrally as one piece with said bottom wall, said bottom wall and said surrounding wall cooperatively defining a receiving space, said bottom wall including a first support disposed in said receiving space, said main surrounding wall including a second support disposed in said receiving space and spacedly above said first support, wherein said main surrounding wall includes a left wall, a right wall, a front wall and a rear wall, said rear wall including a positioning structure to position said backlight module, said positioning structure includes a positioning groove and a positioning stud provided in said positioning groove;
• a said backlight module supported on said first support, said backlight module including an optical film layer that has a projection engaged to said positioning groove and formed with a positioning hole for extension of said positioning stud therethrough;
• and
• a liquid crystal display panel supported on said second support so that said liquid crystal display panel is positioned above said backlight module;
• wherein each of said first support and said second support has a horizontal support face;
• wherein said backlight module includes a light guide plate having a lateral side, and a light-emitting unit disposed on said lateral side, said main surrounding wall being recessed to form a cavity that is spacedly below said second support, said light-emitting unit being disposed in said cavity;
• and
• wherein said light guide plate further has a bottom side connected to a bottom end of said lateral side, said light-emitting unit including a flexible circuit board abutting against said first support, and a light-emitting diode disposed on a top side of said flexible circuit board and corresponding in position to said lateral side of said light guide plate, said liquid crystal display device further comprising an adhesive piece adhered to and disposed between said bottom side of said light guide plate and said flexible circuit board.
