<P>PROBLEM TO BE SOLVED: To suppress the fluctuation in holding potential due to capacitive coupling in a light emitting display device of an active matrix type. <P>SOLUTION: In the display device, a pixel 3 includes a light emitting element, a holding capacitor 7, an active element 8 for sampling, and an active element 9 for driving. The active element 8 for sampling, when selected by the scanning wiring 1, operates to sample a vide signal from signal wiring 2 and holds the signal in the holding capacitor 7. The active element 9 for driving drives the light emitting element according to the video signal held in the holding capacitor 7. The holding capacitor 7 has a laminated structure holding a dielectric film between an upper electrode 7T and a lower electrode 7B and is disposed below the signal wiring 2 so as to be superposed thereon. The lower electrode 7B is connected to the active element 8 and the upper electrode 7T is connected to the power source supply wiring 4. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
