Document Type and Number:
WIPO Patent Application WO/2020/194706
Kind Code:
A1
Abstract:
A TFT layer (17) in an organic EL display device (1) includes: an initialization power supply wire (53); a second interlayer insulating film (35) that covers the initialization power supply wire; a source wire (59) provided on the second interlayer insulating film; a low-level power supply wire (11) provided via a first interlayer insulating film (31) in a layer lower than the initialization power supply wire; and a frame capacitor (85). The frame capacitor has a first frame capacitance electrode (57) that is made of the same material and is arranged in the same layer as the initialization power supply wire and a second frame capacitance electrode (67) that faces the first frame capacitance electrode via the second interlayer insulating film, and is made of the same material and arranged in the same layer as the source wire; the first frame capacitance electrode is electrically connected to a high-level power supply wire and the second frame capacitance electrode is electrically connected to the low-level power supply wire, respectively.
