Display device and touch display panel

A touch display panel comprising:

• a display panel including a substrate, a light emitting element layer in which a light emitting element is located on the substrate, and a pixel driving circuit layer in which a thin film transistor configured to drive the light emitting element is located, the display panel having a display area and a bending area, which are defined therein, wherein at least one of a plurality of pixels including the light emitting element and a pixel driving circuit of the pixel driving circuit layer is in the display area, and the bending area in which the substrate is bent toward a rear surface is included in a non-display area at a periphery of the display area;
• and
• a touch panel including a first touch electrode at a front surface of the display panel and an inorganic layer covering the first touch electrode,
• wherein a contact hole overlapping a connection line of the display panel, which extends across the bending area, is located in the non-display area of the display panel,
• wherein the inorganic layer overlaps at least a partial area of the non-display area of the display panel, and one side end of the inorganic layer is at an outside of the bending area and the contact hole,
• wherein the one side end of the inorganic layer is disposed between the display area and the bending area,
• wherein the pixel driving circuit layer includes:
• a semiconductor layer including a channel region overlapping with a gate electrode, and a source region and a drain region, which are at both sides of the channel region;
• a first source-drain electrode layer constituting a source electrode electrically connected to the source region of the semiconductor layer and a drain electrode electrically connected to the drain region of the semiconductor layer;
• a first via layer covering the first source-drain electrode layer;
• a second source-drain electrode layer electrically connected to the first source-drain electrode layer in an area in which at least a portion of the first via layer is removed;
• and
• a second via layer as an organic layer, located over the second source-drain electrode layer, and
• wherein the inorganic layer is on the second via layer;
• and
• a passivation layer over the inorganic layer,
• wherein one side end of the passivation layer is at an outside of the bending area,
• wherein the one side end of the passivation layer is between the one side end of the inorganic layer and the bending area.
