Title:
平板液晶アンテナ及びその製造方法
Document Type and Number:
Japanese Patent JP7042342
Kind Code:
B2
Abstract:
The present disclosure provides a manufacturing method of a flat panel liquid crystal antenna, including the following steps: providing a first substrate, wherein the two sides of the first substrate are provided with a first metal film layer and a third metal film layer respectively; simultaneously patterning the metal film layer on the two sides to obtain a patterned first metal film layer and a patterned third metal film layer; providing a second substrate, wherein one side of the second substrate is provided with a second metal film layer; patterning the second metal film layer to obtain a patterned second metal film layer; and oppositely bonding the first substrate and the second substrate to form a liquid crystal cell, and preparing a liquid crystal layer. The present disclosure also provides a flat panel liquid crystal antenna by using the above method. Through structural improvement, simultaneous patterning of the metal on the two sides is made possible, most low-efficiency yellow-light procedures are omitted, and time for busy waiting and model switching is saved. The flat panel liquid crystal antenna can be manufactured on a large scale, the manufacturing efficiency is improved, and the manufacturing cost is reduced.
