ABSTRACT:
The invention provides a display unit which can improve reliability and reduce a frame area by forming a protective film in a uniform film thickness over an entire display area, and its manufacturing method. An end face of the protective film is formed along a vertical plane including a corresponding end face of a sealing substrate. The end face of the protective film is formed into an approximately vertical cross section in the position of the end face of the sealing substrate, and the entire display area is covered with the protective film in a uniform film thickness. It is preferable that a distance between a lower end of the end face and the vertical plane is set to 2 mm or less. It is preferable that the end face of the protective film is formed by anisotropic etching using the sealing substrate as a mask, after the protective film is formed over a whole face of a driving substrate.
