Display apparatus and method of manufacturing the same

A method of manufacturing a display apparatus, the method comprising:

• forming a lower metal layer on an upper surface of a substrate,
• wherein the substrate comprises a main display area, a component area, and a peripheral area,
• wherein the component area comprises a transmission area, and the peripheral area is arranged outside the main display area,
• wherein the lower metal layer is formed in the component area, and the lower metal layer comprises a first metal layer and a second metal layer;
• forming a conductive material layer on the substrate in the main display area and on the lower metal layer in the component area;
• forming a pixel electrode by removing at least a portion of the conductive material layer and by removing the second metal layer from the transmission area;
• forming an organic functional layer, an opposite electrode, and an upper layer on an entirety of the upper surface of the substrate,
• wherein the organic functional layer, the opposite electrode, and the upper layer cover the pixel electrode and the first metal layer;
• and
• irradiating a lower surface of the substrate that is opposite to the upper surface of the substrate in the transmission area with a laser beam.
