Embodiment Construction

[0044] Please refer to Figure 4a In one embodiment of the present invention, the transflective liquid crystal display 400 includes an active element array substrate 410, an opposite substrate 420, and a liquid crystal layer 440 disposed between the two substrates 410 and 420. The liquid crystal layer 440 includes, for example, a positive-type liquid crystal molecules or negative liquid crystal molecules. An upper polarizer 574 is disposed above the opposite substrate 420 , and an upper retardation plate 584 is disposed between the upper polarizer 574 and the opposite substrate 420 . A lower polarizer 572 is disposed under the active element array substrate 410 , and the lower phase retardation plate 582 is disposed between the active element array substrate 410 and the lower polarizer 572 . Please refer to Figure 4b On the active element array substrate 410, there are a plurality of scan lines 450 and a plurality of data lines 460 facing the opposite substrate 420, and a pi...

Abstract

The invention provides a semi-penetrating LCD. By setting a resistor between a penetrating electrode and a reflecting board, or by connecting in a floating and insulated way the reflecting board abovethe penetrating electrode and a grounding electrode, and adjusting the electric field size in the reflecting zone, the phase delay of the liquid crystal layer in the reflecting zone and the penetrating zone is adjusted, so that the thickness of the penetrating zone is actually same with that of the reflecting zone, this avoids the complicated making process for two layers of gap.

Description

technical field [0001] The present invention relates to a liquid crystal display, in particular to a transflective liquid crystal display. Background technique [0002] Referring to FIG. 1 , the conventional double-layer liquid crystal cell transflective liquid crystal display 100 includes two polarizers 132 and 134 , and two compensation films 122 and 124 are disposed between the two polarizers 132 and 134 . The two substrates 112 and 114 are sandwiched between the two compensation films 122 and 124 , a liquid crystal layer 140 with a thickness of d is arranged between the two substrates 112 and 114 , and a reflector with a plurality of openings is arranged on the substrate 114 . plate 150. The light 160 provided by the backlight source (not shown) passes through the substrate 114, the opening of the reflector 150 and the liquid crystal layer 140, and reaches the eyes of the observer; the external light 170 passes through the substrate 112 and the liquid crystal layer 140,...
