In the current display industry, the liquid crystal display (LCD) or thin-film transistor liquid crystal display (TFT-LCD) has gradually replaced the cathode ray tube (CRT) to become a mainstream product due to its excellent properties of low radiation and low power consumption. Liquid crystal displays (LCDs) are used in a wide variety of commercial applications, including portable and laptop computers, desktop computers, PDAs (personal digital assistant), palm-top computers, cellular phones, wristwatches, camcorders, and television screens. A liquid crystal display generally includes two substrates and a liquid crystal layer interposed therebetween. The upper substrate has a color filter, and the lower substrate has a thin film transistor (TFT) as a switching element. The liquid crystal display displays an image by applying a voltage to the pixel and common electrodes to align the liquid crystal molecules of the liquid crystal material layer to control transmission of light. Different voltages are applied to the common electrode and the pixel electrodes to generate electric field. The changes of the strength and/or the direction of the electric field change the orientations of liquid crystal molecules to vary the transmittance of light passing through the liquid crystal layer. Accordingly, desired images are obtained by adjusting the difference between the pixel electrodes and the common electrode. There're various types of LCD displays. From the standpoint of structure, there is the direct-view type in which a user views the display itself directly, and the projection type in which a user views images projected on a screen. The widely used direct-view type LCD includes the transmission type (transmissive) LCD having a backlight. In contrast to the transmissive liquid crystal display device, the reflective liquid crystal display device does not require a backlight for display, and therefore can reduce the power consumption of the light source. The unnecessity of the backlight further characterizes the reflective liquid crystal display device by allowing it to be more compact and lightweight. The reflective liquid crystal display device has lower the power consumption, and is suitably used in equipment which needs to be lightweight and thin.
