Abstract: Provided is a method for forming one or more layers by including a single procedure of coating, pre-baking, exposure, development, and post-heat treatment, thereby reducing the process time and implementing a coloring pattern capable of making colors vivid and increasing the reliability and lifespan of a display on an electrode substrate, wherein specifically, the processes of two layers of PDL and CS of an organic light-emitting diode panel are integrated into one, and the UV active ray transmittance of the photomask is adjusted to 0% (non-exposed portion), 20-50% (half-tone), and 100% (full-tone) to create a step height of a pattern after exposure, thereby forming two layers with a single exposure, thereby reducing the process time.

Abstract: An embodiment of the disclosure provides AgInGaS quantum dots, a method for preparing the same, and an electronic device capable of controlling the emission wavelength according to the composition of Ag, In, and Ga precursors constituting a quantum dot core.
