An organic EL device is fabricated by a novel method to reduce the decrease or the dispersion of the luminance of the organic EL device caused by the voltage drop. A display apparatus comprises: optical elements; a power supply line which supplies electrical energy to each of the optical elements; and a signal line which transmits a control signal to each of the optical elements. The resistance of the power supply line is lower than the resistance of the signal line. The cross section of the power supply line may be enlarged, or the resistivity of the constitutional material of the power supply line may be lowered to lower the resistance of the power supply line. |
