Cushion plate and display device including the same

A display device comprising:

• a display panel;
• and
• a cushion plate disposed on a back surface of the display panel,
• wherein the cushion plate includes:
• an impact-absorbing layer disposed on the back surface of the display panel;
• a first metal layer disposed on the impact-absorbing layer;
• and
• a second metal layer disposed on the first metal layer and having higher thermal conductivity than the first metal layer,
• wherein the impact-absorbing layer, the first metal layer, and the second metal layer have a first curvature area,
• wherein at least one perforated pattern is disposed in an area of the first metal layer corresponding to the first curvature area.

A display device comprising:

• a display panel including a first curvature area and a second curvature area, wherein the first curvature area has a radius of curvature equal to or smaller than a reference radius of curvature and the second curvature area has a radius of curvature greater than the reference radius of curvature;
• and
• a cushion plate disposed on a back surface of the display panel,
• wherein the cushion plate includes:
• an impact-absorbing layer disposed on the back surface of the display panel;
• a first metal layer disposed on the impact-absorbing layer and having a strength greater than a reference strength;
• and
• a second metal layer disposed on the first metal layer and having smaller strength and higher thermal conductivity than the first metal layer,
• wherein at least one perforated pattern is disposed in an area of the first metal layer corresponding to the first curvature area.
