PURPOSE: An active matrix type organic electro-luminescence device is provided to reduce the voltage applied between both ends of a storage capacitor and a difference between the left and the right luminance by two switching TFTs and a dual gate method. CONSTITUTION: An active matrix type organic electro-luminescence device includes a substrate(100), a gate line(20), a data line(10), the first switching TFT, the second switching TFT, an LED, the first driving TFT(D1), the second driving TFT(D2), a power line, and a capacitor. The gate line(20) and the data line(10) are formed on the substrate(100) to define a pixel region. The first switching TFT is connected to the gate line(20) and the data line(10). The second switching TFT is connected to the first switching TFT and the gate line(20). The LED has a cathode connected to the ground. The first driving TFT(D1) is connected to an anode of the LED. The second driving TFT(D2) is connected to the first driving TFT(D1) and a drain electrode of the first switching TFT. The power line has the first branch point and the second branch point. The capacitor is installed between the first branch point and the second branch point. of the power line.
