Abstract

The present invention provides a glass substrate which enables to manufacture a FPD in keeping cost low and in efficient, and to provide an efficient manufacturing method of a glass substrate. The method for manufacturing a glass substrate by fusion process comprising the following steps; flowing fused glass into a fusion pipe, and gradually cooling and solidifying the fused glass by flowing downward from the fusion pipe, wherein forming an asperity on a surface of the glass substrate by fastening and pressing the glass toward a direction of thickness of the glass with a pair of transfer rollers during the glass is flowing down from the fusion pipe.

Description

technical field [0001] The present invention relates to a glass substrate used in a flat panel display device (FPD) such as a liquid crystal panel, and a manufacturing method thereof, and more particularly to a glass substrate for a large FPD such as a television or a computer monitor. Background technique [0002] In recent years, the popularity of FPDs such as liquid crystal and plasma methods has been extremely fast, especially recently, a new generation of FPD field emission displays (Field Emission Display) has been launched, which has prompted related research and development to become more popular. [0003] In order to manufacture these FPDs, it is necessary to form a high-precision fine pattern on the surface of a flat glass substrate. Take a TFT liquid crystal element as an example for illustration. In a TFT liquid crystal element, a large number of thin film transistors (TFTs) are precisely arranged on the surface of a glass substrate so as to correspond to each p...
