THE FLEXIBLE DISPLAY SUBSTRATE

摘要

PURPOSE: A flexible display substrate with high thermal transmittance and low coefficient of thermal expansion is provided to have excellent thermal stability and to maintain excellent optical property. CONSTITUTION: A flexible display substrate comprises a glass fiber layer and a resin layer formed on both sides of the glass fiber layer. The resin layer includes 25-400 parts by weight of unit structure from monomers of chemical formula 1 and 100 parts by weight of unit structure from acryl based monomers. The resin layer includes a compound having the weight-average molecular weight of 500-1000000. In the chemical formula 1, R1 to R6 are respectively substituted with hydrogen or a connecting group, or a hydrocarbon group having carbon number 1-10 which are not substituted. The connecting group includes oxygen, nitrogen, sulfur or silicon.
