Abstract
The present invention provides a manufacturing method for LCD panel by coating the first sealant having electrical conductibility on the PSVA testing pad of the lower substrate or on the position of the upper substrate corresponding to the PSVA testing pad of the lower substrate such that the PSVA testing pad electrically connects to the transparent electrode through the first sealant. The present invention also provides a manufacturing method for the LCD device and a manufacturing equipment for the LCD panel. By the above ways, the present invention can improve the uneven phenomenon around the screen of the active viewing area of LCD panel and reduce the occurrence of broken bright spot and realize narrow frame design of the LCD panel.
