Abstract
本揭示公开一种薄膜晶体管液晶显示器,其包含一第一基板。所述第一基板包含一显示区及围绕所述显示区的一非显示区。所述显示区设有一薄膜晶体管。所述非显示区设有一第一公共电极、一连接垫及一弧形凸起。所述连接垫设置于非显示区远离显示区的一侧,且设置于所述第一公共电极上,用以连接于一公共电压产生电路。所述弧形凸起设置于非显示区近显示区的一侧。本揭示的薄膜晶体管液晶显示器藉由弧形凸起的设置避免了在第一基板的显示区涂布配向液时,配向液扩散到非显示区的连接垫而导致显示异常。

本揭示涉及薄膜晶体管液晶显示器(thin-film transistor liquid-crystaldisplay,TFT-LCD)技术领域,特别是涉及一种薄膜晶体管液晶显示器。
背景技术
在现成的薄膜晶体管液晶显示器制程中,为使液晶(liquid crystal)在彩色滤光片(color filter,CF)基板与薄膜晶体管(thin film transistor,TFT)阵列基板间的排列方向一致,会在CF基板及TFT阵列基板对盒前,将配向液涂布在CF基板及TFT阵列基板面向液晶的表面上并进行配向以形成配向膜。喷印(inkjet printing)是印刷配向液的常用工艺,具有印刷效率高及配向液利用率高等优点。然而喷印时,配向液会自由扩散而形成一不规则边缘区域。此不规则边缘区域中的配向液厚度不均,因而需要将不规则边缘区域尽量外扩来降低平均厚度以避免影响盒厚(cell gap)的均一性。一般而言,不规则边缘区域需扩散至距显示区(active area)边缘1.2-2.4mm处,才不会影响盒厚的均一性。因此,对于边框(非显示区)宽度小于2.4mm的窄边框产品,在TFT阵列基板的显示区喷印配向液时,配向液易扩散到设置于非显示区的连接垫(transfer pad)。因配向液具有绝缘性,当配向液覆盖连接垫时,会导致连接垫与导电粒子导通不良,使得TFT阵列基板上的信号无法经由连接垫及导电粒子导通至CF基板的公共电极,进而造成显示异常。
