Abstract:
1. An organic electroluminescent light emitting display device, comprising: a substrate having a main surface; a plurality of pixels arranged two-dimensionally on the main surface of the substrate; a plurality of scanning signal lines arranged in parallel in a first direction on the main surface of the substrate; a plurality of data signal lines arranged in parallel in a second direction which intersects the first direction on the main surface of the substrate; and a plurality of current supply lines arranged on the main surface of the substrate; wherein each of the plurality of pixels comprises: a first active element; a second active element; and an organic electroluminescent element connected to one of the plurality of current supply lines via the second active element, and wherein a gate of the second active element is connected to a capacitor, the capacitor is connected to one of the plurality of scanning signal lines via the first active element, the first active element comprises a gate electrode, the gate electrode being a part of the one of the plurality of scanning signal lines or being connected to one of the plurality of scanning signal lines, the scanning signal lines include a first portion and a second portion in each of the plurality of pixels, and a width of the second portion is wider than the first portion, and the current supply line has a branch line, and wherein the scanning signal line extends along the branch line of the current supply line.
