Liquid crystal display device and method of manufacturing the same

摘要

In a method of manufacturing a liquid crystal display device, a seal material is formed by drawing on a first substrate. A starting point and a terminal point of the drawing overlap forming a closing portion. The seal material is obliquely drawn so as to depart from an active area as the drawing departs from the closing portion. After drawing the seal material so as to surround the active area, the seal material is obliquely drawn so as to close to the active area as the drawing closes to the closing portion. The liquid crystal material is dropped in the inside surrounded with the seal material. After that, a second substrate is arranged on the seal material and the liquid crystal material. Then, the first substrate and the second substrate are attached by curing the seal material.

主权项

1. A method of manufacturing a liquid crystal display device, comprising the steps:
preparing a first substrate including an active area substantially in the shape of a rectangle, a plurality of pixel electrodes arranged in a matrix shape in the active area; forming a seal material by;
drawing the seal material in parallel with a first end of the active area after obliquely drawing so as to depart from the active area by setting an outside position of a first corner portion of the active area to a starting point,drawing the seal material in parallel with a second end of the active area after passing outside of a second corner portion of the active area,drawing the seal material in parallel with a third end of the active area after passing outside of a third corner portion of the active area,drawing the seal material in parallel with a fourth end of the active area after passing outside of a fourth corner portion of the active area, andobliquely drawing the seal material so as to close to the active area as the drawing closes to the first corner portion by setting a position which overlaps with the starting point to a terminal point after drawing the seal material in parallel with a fourth end of the active area, wherein the seal material is drawn in a crooked shape apart from the first corner portion, dropping liquid crystal material in the inside surrounded with the seal material; arranging a second substrate on the seal material and the liquid crystal material; and attaching the first substrate and the second substrate by curing the seal material.
