Abstract: A method of simultaneously fabricating a photospacer and a bump applicable on a substrate with a photoresist layer formed thereon. A photomask is provided with a first mask pattern and a second mask pattern thereon, wherein the first mask pattern for the formation of the bump includes a plurality of light-shielding units constituting a first shape, and the second mask pattern for the formation of the photospacer is composed of a light-shielding pattern with a second shape. The photomask is then applied on the photoresist layer to perform photolithography, thereby fabricating the photospacer and the bump simultaneously. According to the method, only one photolithography step is required to fabricate the photospacer and bump of different thickness, such that yield is increased and cost is lowered.

Abstract: A wide-viewing angle display device serves as a multi-domain vertical alignment (MVA) mode liquid crystal display (LCD) device or an in-plane switching (IPS) mode liquid crystal display (LCD) device. A plurality of protrusions is formed on the inner surface of the glass substrate, and an electrode array is formed on the tops of the protrusions. Thus, the electrodes are suspended in the liquid crystal cell gap, and a transverse electrical field is generated by the electrodes to drive the liquid crystal molecules.
