Abstract
A method for producing a liquid crystal panel by forming a plurality of liquid crystal sealing-in areas between a transparent pair of large-area substrates and dividing the liquid crystal sealing-in areas into separate liquid crystal sealing-in areas. The method includes (A) forming transparent electrodes which form a plurality of liquid crystal panels on a surface of each of the large-area substrates, (B) forming seals, each of which surround the transparent electrode required to form one liquid crystal panel, on one of the large-area substrates in order to form liquid crystal injection openings, and forming liquid crystal injection openings in the seals, (C) bonding together the large-area substrates such that their transparent electrodes face each other, with the seals interposed therebetween, (D) removing a portion of one of the pair of large-area substrates such that the liquid crystal injection opening is exposed to the outside, (E) injecting liquid crystal into the liquid crystal sealing-in area through the liquid crystal injection opening exposed to the outside, and then sealing the liquid crystal injection opening with a sealing agent, and (F) dividing the pair of large-area substrates into separate panels after the liquid crystal injection. According to this method, liquid crystal injection can be performed without completely cutting the large-area liquid crystal panel so that the production steps are simplified.
