  • Display panel, method of manufacturing the same, and liquid crystal display panel
    Patent number: 9285619
    Abstract: A liquid crystal display panel includes a thin film transistor disposed on an insulating substrate in a display region, an external wiring for connecting the thin film transistor to a terminal electrode, and a planarized film disposed on the thin film transistor, and having a planarized upper surface. The planarized film is not disposed, or a planarized film having a smaller film thickness than that of the planarized film in the display region is disposed, above the external wiring in a frame region.
