Abstract

Provided is a glass substrate having low charging properties. The glass substrate is characterized by comprising, in terms of mass%, from 1.7% to less than 9% of B2O3, not more than 0.01% of Li2O, 0.001-0.03% of Na2O, 0.0001-0.007% of K2O, 0.0011-0.035% of Na2O+K2O and more than 0% to 0.4% of SnO2 as glass composition.

Description

technical field [0001] The present invention relates to a glass substrate, and particularly relates to a glass substrate suitable for all substrates of displays including organic EL displays. Background technique [0002] Electronic devices such as organic EL displays are thin, excellent in animation display, and consume less power, so they are used in displays such as TVs and smartphones. [0003] As a substrate of an organic EL display, a glass substrate is widely used. The glass substrate for this application mainly requires the following characteristics. [0004] (1) In order to prevent the diffusion of alkali ions in the semiconductor material after film formation in the heat treatment process, the content of alkali metal oxide is small, [0005] (2) In order to make glass substrates inexpensive, excellent production efficiency is required, especially excellent devitrification resistance and melting properties, [0006] (3) In the p-Si / a-Si TFT manufacturing process,...
