FLEXIBLE SUBSTRATE AND DISPLAY APPARATUS COMPRISING THE SAME

摘要

PURPOSE: A flexible substrate is provided to reduce cyclization deformation and pyrolysis under a high temperature environment and increase transparency, flexibility, lightness and heat resistance. CONSTITUTION: A flexible substrate (10) comprises a matrix (1) and reinforcing material (2) which is included in the matrix. When the flexible substrate measured by thermogravimetric analysis (TGA), a weight change rate represented by an equation 1 is less than 1% at a temperature of 300°C. The weight change rate is 0.2-1%. The matrix comprises polyorganosiloxane resin replaced by halogen. The display device comprises the flexible substrate.
