  • Method of fabricating thin film transistor substrate and organic light emitting display device using the same
    Patent number: 8969128
    Abstract: A method of fabricating a thin film transistor substrate includes: forming a polymer layer on a glass substrate; forming a passivation layer on the polymer layer; forming a thin film transistor array on the passivation layer; and separating the glass substrate from the polymer layer by irradiating a laser from a rear surface of the glass substrate.
