A transflective liquid crystal display device. A first substrate having viewing and peripheral areas is provided. The viewing area comprises transmissive and reflective regions. A backlight device is disposed under the first substrate, used to provide a backlight passing through the transmissive region. A power management controller connects the backlight device to control an intensity of the backlight. At least one photodetector is formed on the first substrate in the peripheral area, wherein the photodetector detects an intensity of ambient light above the first substrate, and then provides a corresponding signal to the power management controller to control the intensity of the backlight. According to the invention, the intensity of the backlight automatically becomes greater when the intensity of the ambient light becomes lower, and the intensity of the backlight automatically becomes lower when the intensity of the ambient light becomes greater.

Transflective liquid crystal display device and method of fabricating the same

A transflective liquid crystal display device implementing a color filter having various thicknesses. An insulating layer is formed on a lower substrate. A lower electrode is formed on the insulating layer, wherein the lower electrode has a transmissive portion and a reflective portion. An upper substrate opposing the lower substrate is provided, wherein a side of the upper substrate has a color filter having various thicknesses. A planarization layer is formed on the color filter, wherein the planarization layer is opposite to the lower substrate. An upper electrode is formed on the planarization layer. A liquid crystal layer is interposed between the upper and lower substrates.
