DISPLAY DEVICE AND METHOD FOR PREPARING THE SAME

摘要

A substrate for a display device of the present invention has a lamination structure where a matrix; an interface layer; and a coating layer are successively stacked. The matrix includes a silicon-based rubber. The interface layer includes a silicon-based rubber of which density is greater than that of the matrix. The flatness (Ra) of the coating layer is 30 nm or less. The substrate for a display device of the present invention is to improve surface bend by using a specific plasma process.
