Abstract
The invention provides a luminous device that is able to effectively utilize a display surface without causing abnormal display of the image, such as decrease of contrast, by stabilizing supply of the image signal by reducing the parasitic capacitance between the wiring lines. The invention also provides electronic appliances including the luminous device. A scanning line 101 to supply a scanning signal to a switching element, such as a TFT, for the pixel is formed under a bank (dummy bank) provided between the luminous elements and partitioning between the luminous elements. A cathode is formed above the bank and on the luminous element (dummy luminous element). The parasitic capacitance between the cathode and scanning line can be reduced by placing the scanning line under the bank.
