Claim:
1. A transparent display substrate, comprising: a base substrate including a pixel area and a transmission area; a buffer layer on the base substrate, the buffer layer including silicon oxynitride; a pixel circuit on the pixel area of the base substrate; an insulation layer covering the pixel circuit on the base substrate, the insulation layer including a gate insulation layer and an insulating interlayer, the gate insulation layer including silicon oxynitride; a pixel electrode disposed only in the pixel area of the base substrate, the pixel electrode being electrically connected to the pixel circuit at least partially through the insulation layer; and a transmitting layer structure selectively disposed on the transmission area of the base substrate, the transmitting layer structure consisting essentially of silicon oxynitride, wherein at least one of the buffer layer and the gate insulation layer include a relative vertical concentration gradient of oxygen and nitrogen such that:
