More specifically, the present invention relates to a half-transflective liquid crystal display. [Prior Art] In order to conform to the lifestyle of modern people, video or imaging devices have become lighter and smaller. Despite the many advantages of conventional cathode ray tubes (CRTs), the design of electronic grabs appears to be heavy and bulky. In addition, due to the generation of some harmful rays, there is always a danger of harming the eyes of the audience. With the dramatic advancement in semiconductor device and optoelectronic device manufacturing technologies, such as liquid crystal display (LCD), organic light emitting display (〇led) and plasma display panel (PDP), it has gradually become a mainstream display product. Depending on the light source used, liquid crystal displays can be divided into three types: reflective liquid crystal displays, transmissive liquid crystal displays, and transflective liquid crystal displays. In the case of a transflective liquid crystal display, the transflective liquid crystal display mainly includes a transflective liquid crystal panel and a backlight unit. The transflective liquid crystal display panel includes a thin film transistor array, a color filter, and a liquid crystal layer sandwiched therebetween. The backlight unit provides a surface light source to illuminate the transflective liquid crystal display panel to display an image. In particular, the thin film transistor array includes a plurality of halogens each having a transmissive region and a reflective region' and wherein the thickness of the liquid crystal layer on the transmissive region is often different from the thickness of the liquid crystal layer on the reflective region. Figure 1 is a cross-sectional view of a conventional liquid crystal display.

Since the opposite substrate is disposed between the backlight unit and the filament array board, the light traveling in the direction of the main (four) to the liquid crystal display surface (four) can be reflected back to the backlight unit by the reflection sheet to be repeated. Therefore, the aperture ratio of the liquid crystal display panel can be effectively improved. Further, an optical film (for example, a partial polarizer or an optical compensation sheet) is disposed on the inner surface of the opposite substrate and does not collect a quarter-wave plate attached to the outer surface of the opposite substrate. In this way, the light reflected by the inner reflection sheet can be reused.

The optical film is used in combination with a (four) reflective sheet, but can also be used in conjunction with a (four) reflective sheet. Although the pixel_element substrate is an active array substrate, other types of 昼-switches can be configured on the array board.
