Liquid crystal display device and manufacturing method thereof

Abstract

The invention discloses a liquid crystal display device and a manufacturing method thereof, wherein a single common line is formed in the center of a substrate, which results in an increase in aperture ratio and transmittance. The liquid crystal display device includes: a single common line, located in the center of the substrate; a first group of unit pixels, located in the right half of the substrate based on the common line, and a second group of unit pixels, located in the left side of the substrate based on the common line In the half, each unit pixel is formed by a plurality of gate lines and data lines perpendicularly intersecting each other; and a plurality of thin film transistors are formed on the right side of each unit pixel of the first group and the left side of each unit pixel of the second group .

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to a liquid crystal display device in which a single common line parallel to a grid line is formed in the center of a substrate so as to improve light transmittance and a manufacturing method thereof. Background technique [0002] With the development of the information age, the demand for display devices is gradually increasing. Accordingly, various flat panel display devices, such as liquid crystal displays (LCDs), plasma display panels (PDPs), electroluminescent display devices (ELDs), and vacuum fluorescent display (VFD) devices, have recently been studied and considered as Display devices are used in various devices. [0003] Among the above display devices, liquid crystal display devices are currently being used as portable image display devices instead of cathode ray tubes (CRTs) due to favorable features and advantages such as high resolution, ultra-thin design, low weight...

AI Technical Summary

Problems solved by technology

However, since the common lines CL are set to be equal in number to the gate lines GL, the conventional liquid crystal display device described above has a reduced aperture ratio due to the area of ​​the common lines CL in each unit pixel.

In particular, the area of ​​each unit pixel of a high-resolution display device is smaller than that of a low-resolution display device, so the area of ​​the common line CL based on each unit pixel is smaller in a high-resolution display device than in a low-resolution display device. increases, which leads to a significant decrease in light transmittance
