Abstract: The use of liquid crystal glass substrate was introduced and development status and trends of liquid crystal glass substrate in China were analyzed.On the basis of that，the market demand of liquid crystal level high-purity strontium salt which is one of raw materials of liquid crystal glass substrate was predicted.The production technologies，main characteristics，and technical development trends of liquid crystal level high-purity strontium salt were introduced in detail. The production status of liquid crystal level high-purity strontium salt in China was emphatically introduced and its domestic development prospect was also predicted.In the meanwhile，some problems and suggestions of the industry were put forward， aiming at promoting sustainable and healthy development of liquid crystal level high-purity strontium salt.

Key words: liquid crystal level, strontium salt, development trend
