Method of manufacturing a display device with transmissive and reflective regions
View Patent ↗A display device formed by plural pixels that have reflective regions and transmissive regions is disclosed. The display device includes, in each of the pixels: an element layer formed on a substrate; a planarizing layer formed on the substrate to cover the element layer; and a gap adjusting layer formed on the planarizing layer on the element layer. In the display device, the reflective region is formed by an area including the element layer, the planarizing layer, the gap adjusting layer, and a reflection electrode formed on the gap adjusting layer, and the transmissive region is formed by an area including the planarizing layer formed on the substrate excluding an area in which the gap adjusting layer is formed.
1. A method of manufacturing a display device comprising:
forming, on a substrate, a planarizing layer that covers an element layer formed on the substrate;
forming, in the planarizing layer, a contact hole leading to the element layer;
forming, on the planarizing layer, a pixel electrode connected to the element layer through the contact hole;
forming a gap adjusting layer over the planarizing layer; and
forming, on the gap adjusting layer, a reflection electrode connected to the pixel electrode at one end of the gap adjusting layer,
wherein,
the pixel electrode has a portion that is between the planarizing layer and the gap adjusting layer with respect to a thickness direction of the display device, and
the planarizing layer is formed such that a height from a surface of the substrate to a surface of the planarizing layer in an area in which the gap adjusting layer is formed is larger than a height from the surface of the substrate to a surface of the planarizing layer in an area in which the gap adjusting layer is not formed.
2. The method of manufacturing a display device according to claim 1 , further comprising the step of forming roughness on the gap adjusting layer after forming the gap adjusting layer and before forming the reflection electrode.
