Problems solved by technology

Because the prior art masking process includes the steps of coating PR, exposing PR, and developing PR, an increase in the number of masks leads to an increase in production cost and manufacturing time and a decrease in yield
In addition, the reliability of thin film transistors is also reduced

Embodiment Construction

[0038] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, like reference numbers are used to refer to the same or like parts.

[0039] Figure 4 Shown is a schematic plan view of an array substrate of a liquid crystal display device according to an exemplary embodiment of the present invention. Figure 4 The display area and pad area of ​​the array substrate are shown, and the drive area of ​​the array substrate is not shown for simplicity.

[0040] exist Figure 4 Among them, the gate lines 112 and the data lines 109 are formed in the display area “DPA” of the substrate 101 . A gate pad 170 is formed at one end of the gate line 112 and a data pad 175 is formed at one end of the data line 109 . The gate line 112 crosses the data line 109 to define a pixel region "P". A thin film transistor (TFT) “Tr” as a switching element is connected to the gate line 112 a...

Abstract

A polycrystalline silicon thin film transistor of a bottom gate structure is used as a switching element and a mask having transmissive, half-transmissive and blocking areas is used so that an array substrate for a liquid crystal display device having a monolithic driving circuit can be fabricated through a six-mask process.

Description

[0001] This application claims priority from Korean Patent Application No. 2004-0023444 filed in Korea on Apr. 6, 2004, which is incorporated herein by reference. technical field [0002] The invention relates to a display device and a manufacturing method thereof, in particular to a liquid crystal display device with a driving circuit and a manufacturing method thereof. Background technique [0003] Flat panel display (FPD) devices with good portability and low power consumption have been the subject of recent research and development. Among various types of FPD devices, liquid crystal display (LCD) devices are commonly used as monitors for notebook and desktop computers due to their ability to display high-resolution images, wide color ranges, and moving images. [0004] Generally, an LCD device includes a color filter substrate and an array substrate separated from each other by interposing a liquid crystal layer therebetween, wherein the color filter substrate and the ar...
