Abstract: A display device includes a first substrate including a first contact hole, fan-out lines in a first metal layer, a second substrate on the first metal layer and including a second contact hole, connection lines in a second metal layer and into the second contact hole connected to the fan-out lines, a thin film transistor in an active layer and a third metal layer on the second metal layer, and a flexible film on a surface of the first substrate and into the first contact hole connected to the fan-out lines. An etching angle of the first contact hole between a top surface of the first substrate and an inner surface of the first contact hole is less than an etching angle of the second contact hole between top surfaces of the fan-out lines and an inner surface of the second contact hole.
