  • Publication number: 20240172493
    Abstract: An organic light emitting display device, in which a silicon semiconductor pattern is formed on a buffer layer, and light shielding patterns of a pixel driving thin film transistor and a switching thin film transistor are then formed in the same process by processing portions of the silicon semiconductor pattern such that the portions of the silicon semiconductor pattern have conductivity, is disclosed. In a procedure of forming the silicon semiconductor pattern for formation of the light shielding patterns, a silicon semiconductor pattern, which is disposed under a gate driving thin film transistor, may be formed simultaneously with the former silicon semiconductor pattern, without using an additional silicon semiconductor pattern formation procedure. Accordingly, stack structures, planar design, and processes are simplified and, as such, there are effects of preventing failure occurring due to processes while reducing tact time and costs.
