  • Display panel, display device, input/output device, data processing device, and method for manufacturing the display panel
    Patent number: 10528198
    Abstract: A display panel and the like with a novel structure are provided. In the display panel, a first functional layer includes a pixel circuit and a first insulating film. A second functional layer includes a coloring film and a second insulating film. The first insulating film and the second insulating film each have a thickness of 0.5 ?m to 3 ?m and a Young's modulus of 3 GPa to 12 GPa. A sealing material is provided between a first base and a second base. A structure body is provided between the first base and the second base, and keeps a predetermined gap between the first and second bases. A pixel is surrounded by the first base, the second base, and the sealing material. A display element in the pixel is electrically connected to a pixel circuit and overlaps with a coloring film and a liquid crystal material.
