Abstract
A substrate and a method for producing the same are disclosed herein. In some embodiments, a substrate includes a base layer, a black layer formed on the base layer, and column spacers formed on the black layer, wherein a loss rate of spacers measured by a peel test is 15% or less. The substrate can have excellent adhesiveness of the spacer to the base layer or the black layer and ensuring appropriate darkening properties. The method can effectively produce such a substrate without adverse effects such as occurrence of foreign materials without separate treatment such as heat treatment.
