 摘要
 TFT(Thin film Transistor)技术是二十世纪九十年代发展起来的，采用新材料和新工艺的大规模半导体全集成电路制造技术，是液晶（LC）、无机和有机薄膜电致发光（EL和OEL）平板显示器的基础。TFT是在玻璃或塑料基板等非单晶片上（当然也可以在晶片上）通过溅射、化学沉积工艺形成制造电路必需的各种膜，通过对膜的加工制作大规模半导体集成电路（LSIC）。
 本文主要介绍了TFT的一些简单的基本原理和液晶显示器的制作流程，通过本文，我们可以了解到液晶显示器的一些简单的知识。液晶显示器的成色是三种基本的颜色组成，分别是红、黄、蓝。再通过驱动电路的电压的大小来控制液晶的角度来达到透光率的控制，进而形成各种颜色。在未来的几年内，液晶显示器将成为新的主流产品出现在我们的生活里。

Abstract
 The TFT (Thin film Transistor )technology  was developed since the 1990s ，making use of new materials and new technology for large-scale integrated circuits the entire semiconductor manufacturing technology, based on A liquid crystal (LC), inorganic and organic thin film electroluminescent (EL and OEL) the basis of flat-panel displays. TFT is a membrane by sputtering in a glass or plastic substrate, and other non-single-chip (of course, can also on the chip), creating a chemical deposition process necessary for film circuit, integrated circuits (LSIC) completed through the membrane of the large-scale manufacture semiconductor
     This paper presents some simple and basic principle and production process  of the night crystal display, Through this paper, we can understand that some simple knowledge of Liquid Crystal Display. The condition of the liquid crystal display is composed of three basic colors, namely red, yellow and blue. To drive through the circuit voltage to control the size of the angle of LCD to achieve transparency of control, then a variety of colors. In the next few years, Liquid Crystal Display will become the new mainstream products in our lives.
