Benefits of technology
The patent text describes a method to reduce manufacturing time and cost of a display device, and also to prevent damage to the semiconductor layer during the process. This is achieved by reducing the number of photomasks utilized in the manufacturing process. In addition, the method also includes reducing the area of one pixel and improving the resolution of the display device by reducing the number of openings for contact between different layers stacked on the substrate.
Problems solved by technology
As the number of photomasks utilized in the manufacturing process of the display device increases, a manufacturing time and manufacturing cost of the display device may increase.
