Abstract
A liquid crystal display device including a first substrate having a contact hole and second substrate substantially in parallel with the first substrate. Each substrate has electrodes on an inner side thereof with the electrodes of the first substrate being connected to the electrodes of the second substrate at a location which is close to an edge of the contact hole.
Claims35
A liquid crystal display device, comprising:
- a first transparent substrate having a contact hole;
- a second transparent substrate spaced apart substantially in parallel from said first transparent substrate to form a gap;
