Description

反射式液晶显示面板 技术领域
本发明涉及显示技术领域，尤其涉及一种反射式液晶显示面板。
 背景技术
液晶显示装置（Liquid Crystal Display，LCD）具有机身薄、省电、无辐射等众多优点，得到了广泛的应用，如：移动电话、个人数字助理（PDA）、数字相机、计算机屏幕和笔记本电脑屏幕等。
现有技术中，液晶显示装置一般包括液晶显示面板。液晶显示面板包括相对设置的彩膜基板（Color Filter Substrate）及薄膜晶体管阵列基板（Thin Film Transistor Array Substrate，TFT Array Substrate）以及配置于彩膜基板与TFT阵列基板之间的液晶层（Liquid Crystal Layer），其工作原理是通过在TFT阵列基板的像素电极与彩膜基板的公共电极上施加驱动电压来控制液晶层的液晶分子的旋转，将光线折射出来产生画面。
现有市场上的液晶显示装置大部分为透射式液晶显示装置，透射式液晶显示装置在液晶显示面板的设有TFT阵列基板的一侧设置背光源，且液晶显示面板中TFT阵列基板的像素电极与彩膜基板的公共电极均为透明电极，工作时，背光源发出的光线由液晶显示面板设有TFT阵列基板的一侧射入，透过TFT阵列基板、液晶层及彩膜基板而后射出而显示图像。由于透射式液晶显示装置由背光源提供用于显示的光线，因而具有在弱光或无光环境下显示能力优异的特点，但在强光环境（例如户外日照）下，透射式液晶显示装置往往存在背光亮度不足的问题，严重影响显示效果，此时若单纯的提高背光源的背光亮度，不但对透射式液晶显示装置的显示品质的提升起到的效果较弱，并且由于背光源亮度增加，会大大增加液晶显示装置的耗电量，降低产品的品质。

请参阅图2，本发明第二实施例的反射式液晶显示面板与上述第一实施例的区别在于，所述TFT阵列基板10在钝化层13与像素电极层14之间设有彩色滤光层30。其余结构均与上述第一实施例相同，在此不再赘述。
需要说明的是，本发明的反射式液晶显示面板的第二实施例在工作时，环境光从TFT阵列基板10一侧入射反射式液晶显示面板，经过彩色滤光层30的滤光后穿透液晶层40被反光的公共电极层22反射，而后再次穿透液晶层40及并经彩色滤光层30滤光从TFT阵列基板10一侧射出而进行显示，因此，本发明的反射式液晶显示面板无需设置背光源即可实现显示，面板的整体厚度降低，并且显示功耗较低，同时，由于光线会两次穿过彩色滤光层30，因此，该彩色滤光层30的厚度设置为现有的透射式液晶显示面板的一半即可，进一步降低面板的整体厚度，而且节省了彩色滤光层30的材料成本从而降低产品的成本。本发明的反射式液晶显示面板可直接固定安装在户外的墙面上或路灯等已有的环境光源下方，在白天太阳照射时可直接显示画面，夜晚时可反射环境光源的光线来显示画面。
综上所述，本发明的反射式液晶显示面板包括相对设置的TFT阵列基板及对置基板，TFT阵列基板包括沿靠近对置基板的方向依次设置的第一衬底、TFT阵列层、钝化层及像素电极层，对置基板包括沿靠近TFT阵列基板的方向依次设置的第二衬底及反光的公共电极层，对置基板在公共电极层靠近TFT阵列基板一侧设有彩色滤光层或者 TFT阵列基板在钝化层与像素电极层之间设有彩色滤光层，从而该反射式液晶显示面板工作时，环境光由TFT阵列基板一侧射入并经反光的公共电极反射后由TFT阵列基板一侧出射进行显示，无需设置背光源，显示功耗及产品成本较低。
