Abstract: Certain types of displays such as electrophoretic displays tend to deteriorate if their pixel units are persistently driven by currents flowing in only one direction for the purpose of maintaining (i.e. refreshing) a relatively constant optical state. A first method pulses the pixel unit with a drive pulse of opposed polarity but duration too short (i.e. less than 1/25 second) for a viewer to notice. A second method pulses the pixel unit with a drive pulse of opposed polarity but magnitude to small to effect change in optical state.

Abstract: The present invention is related to a method of fabricating a liquid crystal display device which includes etching an attached substrate using an etchant to make the substrate thin and light. A plurality of main seal patterns are formed on a first substrate and auxiliary seal patterns are formed around each main seal pattern. Thereafter, a second substrate is attached to the first substrate by pressure. Then, an anti-etching material is formed around the sidewalls of the attached substrates. Due to the anti-etching material, an etchant etching the surfaces of the attached substrate does not penetrate into the interval between the first and second substrates.
