A liquid crystal display (LCD) with a built-in touch panel includes an LCD unit, a touch panel and a second polarized plate. The LCD unit includes a lower substrate, an upper substrate, a liquid crystal layer and a first polarized plate. The upper substrate is disposed opposite to the lower substrate, and the liquid crystal layer is disposed between the lower substrate and the upper substrate. The first polarized plate is disposed on the lower substrate and has a first polarized direction. The touch panel is disposed opposite to the LCD unit. The second polarized plate having a second polarized direction is disposed on the touch panel and located between the LCD unit and the touch panel. An intensity of a reflected light occurred in the LCD with the built-in touch panel is relatively low, so that good contrast and visibility are obtained.

A touch display panel and a touch panel therein are provided. The touch panel includes a first transparent supporter plate, a second transparent supporter plate, and a touch module. The second transparent supporter plate and the touch module are disposed over the first transparent supporter plate. The first transparent supporter plate and the second transparent supporter plate have optical anisotropy. The first transparent supporter plate has a first fast axis and a first slow axis, and the second transparent supporter plate has a second fast axis and a second slow axis. A direction of the second fast axis is substantially perpendicular to a direction of the first fast axis, and a direction of the second slow axis is substantially perpendicular to a direction of the first slow axis. The touch panel of the present invention is helpful to improve display quality of the touch display panel having the touch panel.

A liquid crystal display (LCD) including a LCD panel, a first polarizer and a second polarizer respectively disposed at two sides of the LCD, a first a-plate and a second a-plate disposed between the polarizers and LCD panel, a biaxial compensation plate and a c-plate is provided. The biaxial compensation plate is disposed between one of the polarizers and one of the a-plates. The main axis refractive indexes n, nand nof the biaxial compensation plate satisfy the formula of Nz=(n&#x2212;n)/(n&#x2212;n), wherein n&#x3e;nand &#x2212;0.5&#x3c;Nz&#x3c;1. The first c-plate is disposed between one of the a-plates and LCD panel. The LCD of the present invention is capable of widening viewing angles and enhancing display quality.

A liquid crystal display (LCD) including an LCD panel and a back light module is provided. The back light module is disposed below the LCD panel. The back light module includes a planar light source, a reflective polarized light enhancement film, a first prism film and a &#x3bb;/4 phase retardation film. The planar light source is disposed below the LCD panel, while the reflective polarized light enhancement film is disposed between the LCD panel and the planar light source. The first prism film is disposed between the reflective polarized light enhancement film and the planar light source. Besides, the &#x3bb;/4 phase retardation film is disposed between the reflective polarized light enhancement film and the first prism film. The back light module has a relatively high light utilization rate, and the LCD has favorable display luminance.

A liquid crystal display includes a first and a second transparent substrates facing to each other, a liquid crystal layer, a first polarizer, a second polarizer, and a first half wave plate. The liquid crystal layer is interposed between the first and the second transparent substrates. The first polarizer is positioned next to the first transparent substrate and opposite the liquid crystal layer, and the second polarizer is positioned next to the second transparent substrate and opposite the liquid crystal layer. The first half wave plate is provided between the first transparent substrate and the first polarizer to enable the liquid crystal display to have a normally black mode.

A transflective LCD having a dual common-electrode structure has a front substrate, a liquid crystal layer and a rear substrate. The front substrate has multiple first and second common electrodes respectively connected to a first and a second contact pads. The first and second contact pads are respectively connected to two voltage sources to obtain different voltage. The rear substrate has multiple pixels, each has a reflective region and a transmission region. The reflective region is aligned to the first common electrode and the transmission region is aligned to the second common electrode. Since the voltages to the first and second common electrodes are different, the voltages of two liquid crystal capacitors corresponding to the reflective and transmission regions are also different. Therefore, the V-T curves of one pixel are adjustable to be close to each other by supplying different voltages to the first and second common electrodes.
