ABSTRACT:
A liquid crystal display (LCD) device with a freely updated rear liner plate. The bottom of the LCD panel is installed with a freely updated rear liner plate and a rear liner plate positioning means. A rear liner plate positioning means installed on the bottom of the LCD panel includes a rear liner plate inserting opening on the outer wall at one side of the case; a first positioning engaging portion; a second positioning engaging portion; an elastic element provided with an elastic force to eject the rear liner plate upwards; and a pressing mouth communicated with the second positioning engaging portion and the inserting opening of the rear liner plate. The rear liner plate is inserted from the inserting opening. By the first and second positioning engaging portions of the rear liner plate positioning means and the elastic element, the rear liner plate is fixedly secured to the bottom the LCD panel. Moreover, from the pressing mouth, the distal end of the rear liner plate is pressed so that the distal end moves downwards to the rear liner plate inserting opening, thus the rear liner plate is pulled out. The present invention further includes a light source installed between the LCD panel and the rear liner plate positioning means and on the inner wall above the first positioning engaging portion. As the light source emits light to the rear liner plate, then the light is reflected to the LCD panel for increasing the illumination.
