Claims9
An active matrix liquid crystal display panel, comprising:
- a lower substrate having a display portion and a separate periphery portion;
- a plurality of pixel electrodes formed in said display portion on said lower substrate organized in a matrix including columns and rows;
- a plurality of first lines formed on said lower substrate traversing said display portion and extending to said periphery portion, said first lines being connected respectively to said pixel electrodes of each column by first diodes;
- an upper substrate;
- a plurality of second lines formed on a lower surface of said upper substrate, said second lines being provided respectively over each row of said pixel electrodes;
- liquid crystal inserted between said display portion of said lower substrate and said lower surface of said upper substrate;
- a wiring formed on the periphery portion of said lower substrate separately from said pixel electrodes and said first lines, said wiring being being formed to cross said first lines;
- and
- a plurality of second diodes connected between said wiring and said first lines.
