Document Type and Number:
WIPO Patent Application WO/2018/070789
Kind Code:
A1
Abstract:
The present invention relates to a window substrate and a method for producing same and, more specifically, to a window substrate and a method for producing same, the window substrate comprising: a base substrate comprising a display region and a non-display region; a light-blocking pattern disposed on the non-display region on one side of the base substrate and dividing the display region and the non-display region; a first adhesion layer formed across the outer surface of the light-blocking pattern and the one side of the base substrate; a polarization layer superposed on the first adhesion layer; and a touch sensor layer superposed on the polarization layer, wherein the viscoelasticity ratio of the light-blocking pattern to the first adhesion layer is 75,000 or below, and the thickness ratio of the light-blocking pattern to the first adhesion layer is 0.6 or below, thereby removing bubbles in a stepped part and enhancing flexible properties.
