Abstract:
A method for fabricating a superimposed spacing wall-bump structure disposed on two substrates of a multi-domain wide viewing angle liquid crystal display, comprising the steps of:(a) preparing first and second substrates, said first substrate having a pixel electrode layer formed thereon and said second substrate having a common electrode layer formed thereon; (b) manufacturing a first plurality of surrounding wall-bump structures on said pixel electrode layer and a second plurality of central wall-bump structures on said common electrode layer, each of said surrounding wall-bump structures being formed around a pixel area on said pixel electrode layer and a corresponding central wall-bump being formed in a central portion of said pixel area; (c) applying a layer of alignment film on said first plurality of surrounding wall-bump structures and on said second plurality of central wall-bump structures respectively; (d) dispensing conductive epoxy to establish electrical conduction for said first and second substrates; and (e) aligning and pressing said first and second substrates together; wherein each surrounding wall-bump structure superimposes the corresponding central wall-bump structure to form a cell gap.
