液晶显示装置

Abstract

一种液晶显示装置,第一基板的玻璃之上至液晶层之间依次设有底层公共电极、第一绝缘层、第一金属层、第二绝缘层、非晶硅层、第二金属层、第三绝缘层和像素电极(6);所述的底层公共电极为面状公共电极(1),整面设于第一基板的玻璃之上。本发明增加像素电极与公共电极之间的重叠面积,改善像素存储电容值的可调节范围;把线状金属公共电极线改成透明材料的面状公共电极,提高公共电极的供电能力,改善公共电极不同位置的电位均匀性;通过数据线两侧遮光线的合并,提高像素开口率,降低数据线与底层公共电极之间的耦合电容。本发明底层公共电极只需要进行溅射成膜工艺,不需专门的掩模板进行光刻工艺,有效降低了生产成本,提高经济效益。
The invention relates to a liquid crystal display device. A bottom layer common electrode, a first insulating layer, a first metal layer, a second insulating layer, an amorphous silicon layer, a second metal layer, a third insulating layer and a pixel electrode (6) are arranged sequentially from glass of a first substrate to a liquid crystal layer of the first substrate. The bottom layer common electrode is a planar common electrode (1) and is integrally arranged on the glass of the first substrate. In the invention, an overlapping area between the pixel electrode and the common electrode is increased; an adjustable range of a pixel storage capacitance value is improved; a linear metal common electrode line is changed into the planar common electrode made of transparent materials, so thatthe power supply capacity of the common electrode is improved and the potential uniformity at different positions of the common electrode is improved; and by combining light shading lines at both ends of a data line, the pixel aperture opening ratio is improved and a coupling capacitor between the data line and the bottom layer common electrode is reduced. The bottom layer common electrode only needs to be subjected to a sputtering film forming process and does not need to be subjected to a photolithographic process by a special mask plate, so that the production cost is effectively reduced and the economic benefits are improved.
