ABSTRACT:
A matrix-addressed type liquid crystal display device includes a display element conductor pattern deposited on a matrix-addressed substrate and effects display by storing charges into liquid crystal held at the space between the matrix-addressed substrate and an opposing substrate by using a voltage supplied through the display element conductor pattern. The matrix-addressed type liquid crystal display device has a recovery conductor pattern for preventing a line-shape defect in a screen due to a breakage in the display element conductor pattern. The recovery electrode is located below the sealing material. The opposing substrate and the matrix-addressed substrate are aligned with each other at one side thereof, and an inlet for liquid crystal is provided at this aligned side. Liquid crystal is fed into the space between the matrix-addressed substrate and the opposing substrate from a liquid crystal reservoir through the inlet without immersing the substrates in the liquid crystal reservoir.
