Abstract
Abstract An electrode structure on a matrix type liquid crystal display panel includes M column electrodes and N row electrodes both of which cross each other at a right angle to define picture elements via a layer of liquid crystal material. The matrix shaped electrode structure is such that a third picture element C (X m ', X n ') is located between a first picture element A (X m , Y n ) and a second picture element B (X m+1 , Y n+1 ), wherein 1≦m≦M and 1≦n≦N, thus enhancing resolution in vertical and horizontal directions. A diamond shape is exemplary of the possible shapes of the picture elements wherein each pair of the diagonally disposed corners are connected to that of their adjacent elements.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
114 words
A matrix type liquid crystal display device comprising: a plurality of column electrodes; a plurality of row electrodes corresponding to and generally orthagonal to said column electrodes whereby, corresponding row and column electrodes form diamond-shape picture elements; each of said diamond-shaped picture elements having a first pair of opposed apices arranged along a line generally extending in the direction of said column electrodes and a second pair of opposed apices arranged along a line generally extending in the direction of said row electrodes; said first pair of opposed apices of adjacent picture elements being connected to form said column electrodes; and a layer of liquid crystal material disposed between said column and row electrodes.
Claim 2
Dependent Claim
114 words
A matrix type liquid crystal display device comprising: a plurality of column electrodes; a plurality of row electrodes corresponding to and generally orthagonal to said column electrodes whereby, corresponding row and column electrodes form diamond-shape picture elements; each of said diamond-shaped picture elements having a first pair of opposed apices arranged along a line generally extending in the direction of said column electrodes and a second pair of opposed apices arranged along a line generally extending in the direction of said row electrodes; said first pair of opposed apices of adjacent picture elements being connected to form said column electrodes; and a layer of liquid crystal material disposed between said column and row electrodes.
Claim 3
Dependent Claim
20 words
A matrix type liquid crystal display device as in claim 1, wherein said row electrodes are generally zigzag-like in shape.
Claim 4
Dependent Claim
37 words
A matrix type liquid crystal display device as in claim 1, wherein said first pair of opposed apices of adjacent picture elements are connected by a connectin electrode generally extending in the direction of said column electrodes.
Claim 5
Dependent Claim
54 words
A matrix type liquid crystal display device as in claim 1, wherein said first pair of opposed apices of adjacent picture elements are directly connected such that the diagonal side of a first picture element directly connects to the corresponding transversely adjacent diagonal side of an adjacent picture element thereby forming said column electrodes.
Claim 6
Dependent Claim
32 words
A matrix type liquid crystal display device as in claim 1, wherein said first pair of opposed apices of adjacent picture elements are directly connected without the use of a connection electrode.
