A pixel element and a liquid crystal display with discharge function are disclosed. In each of the pixel elements of the liquid crystal display, a transistor is disposed between the common electrode and the pixel electrode. The transistor will be turned on by a discharge signal sent from the master control unit of the liquid crystal display when the liquid crystal display is turned on or turned off, so as to provide the same common voltage to both the common electrode and the pixel electrode. Therefore, the positive and negative charges accumulated in the common electrode and the pixel electrode can be removed and the liquid crystal display is well protected.

A structure and a method of manufacturing the organic electroluminescent (EL) elements, patterns of icons on the display panel of organic EL elements are formed. Initially, ramparts are formed on a continuous surface of a transparent and conductive film, i.e. an indium-tin oxide (ITO) film, and ramparts determine patterns of icons, then organic function layers and electrodes are formed. Processes are compatible to a conventional method of manufacturing an array type display panel, to improve disadvantages of dividing processes of array type display panels and organic EL elements into two portions.
