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

1. 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.

2. A matrix type liquid crystal display device as in claim 1, wherein said row electrodes are generally zigzag-like in shape.

3. 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.

4. 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.

5. 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.
