Active matrix organic EL display device and manufacturing method thereof

aaaAn active matrix organic EL display device includes pixels each having an organic EL element and a pixel circuit including a polysilicon TFT for controlling the organic EL element arranged adjacently in each of the regions partitioned into a matrix shape by data line and gate line that intersect each other. The organic EL element has a cathode arranged in at least a region that excludes a space above the polysilicon TFT. The cathode is arranged continuously over two or more adjacent pixels in the direction of gate line.
