A displaying method for trans-flective type display device is provided. The pixel array of the display device has a selected pixel unit formed by three sub-pixels selected from three basic-color sub-pixels and one enhancement sub-pixel, wherein there is a reflective area within the enhancement sub-pixel. The displaying method includes the following steps. Firstly, an original image having an image data is provided to the display device. Next, when the backlight is turned off, the resolution of the original image is scaled down for obtaining an adjusted image data. Then, another pixel unit consisting of the three basic-color sub-pixels and the enhancement sub-pixel is re-selected, and the driving value of the enhancement sub-pixel is calculated according to the adjusted image data for driving the enhancement sub-pixel.

Displaying method

A closed-cavity liquid-crystal display is provided, which is a liquid-crystal display having a wide angle of view. The liquid-crystal display comprises: an insulator layer formed with a plurality of cavities extending completely through the insulating layer, in which liquid-crystal material is filled into the plurality of cavities; a first substrate, placed on one side of the insulator layer, in which a first electrode is formed on one side of the first substrate near the insulator layer; and a second substrate, placed on the other side of the insulator layer, in which a second electrode is formed on one side of the second substrate near the insulator layer, so that the first electrode and the second electrode are used to drive and vary the alignment of liquid-crystal molecules in the plurality of cavities. The inner circumference of the closed cavity is coated with a homeotropic alignment agent, so that the alignment of the liquid-crystal molecules is circularly symmetric, and the optical performance of the liquid-crystal display is independent of the azimuthal angle.
