Abstract
Disclosed herein is a display apparatus, including, a panel having a plurality of pixels disposed in a matrix and each including a self-luminous element for emitting light, the panel including first to third conductive layers laminated in order on a supporting substrate, a first contact portion between the first and second conductive layers and a second contact portion between the second and third conductive layers being disposed at the same position in a planar direction.
Claims1
A display apparatus comprising:
- a gate electrode of a driving transistor, a source region of the driving transistor is a portion of a polysilicon layer;
- a first electrode of an accumulating capacitor that is physically connected to the gate electrode of the driving transistor, the gate electrode of the driving transistor is a portion of a lower layer and the first electrode of the accumulating capacitor is another portion of the lower layer;
- a first electrode of an additional capacitor, a different portion of the lower layer is the first electrode of the additional capacitor;
- a second electrode of the additional capacitor, a different portion of the polysilicon layer is the second electrode of the additional capacitor;
- a second electrode of the accumulating capacitor that is physically connected to the second electrode of the additional capacitor, another portion of the polysilicon layer is the second electrode of the accumulating capacitor;
- an intermediate layer between the lower layer and an upper layer, the intermediate layer is between the upper layer and the polysilicon layer;
- and
- a first contact hole that at least partially overlaps a second contact hole in a plan view of a display panel, the second contact hole in the plan view of the display panel is larger than the first contact hole,
- wherein a portion of the upper layer in the first contact hole is physically connected to the portion of the intermediate layer,
- wherein the lower layer is a metal and the upper layer is a conductive layer that includes silver, the intermediate layer is a metal layer.
