However, with the conventional method, when the gap material is spread on the board, it is not evenly spread on the board, and there are areas where the gap material is densely spread and areas where the gap material is sparsely spread. mass (group)
In some cases, there may be visible signs of dispersion, making it impossible to obtain an evenly distributed condition. Therefore, if a space is formed by aligning the substrates of a liquid crystal cell with the gap material spread in such a state, a uniform space will not be obtained, which will cause problems in terms of the function of the liquid crystal cell. Furthermore, if there is a group of gap materials, there is a risk of damaging and destroying the substrate on which semiconductor elements such as transistors are formed.
そこで本発明は従来のこの様な欠点を解決する

In order to solve the above problems, this invention provides an obstacle (hereinafter referred to as a dispersion body) in front of the nozzle so that the gap material blown out from the nozzle hits the dispersion body.
The material was scattered so that the gap material was evenly spread over the substrate.
