Abstract:
A thin film transistor array panel device comprises: a base substrate; a barrier layer disposed over the base substrate and comprising a plurality of transparent material layers; and an array of thin film transistors disposed over the barrier layer. A difference between a refractive index of the barrier layer and a refractive index of the base substrate may be within about 6%. The transparent material layers may be arranged such that the transparent material layers having compressive residual stress and the transparent material layers having tensile residual stress are alternately stacked. Each of the transparent material layers may comprise silicon oxynitride (SiON).
