Patent ID: 7274142

Claim:
A display unit, comprising: a driving substrate having a display area and an external connection area spaced by a boundary therebetween; a sealing substrate; and a protective film which covers the display area and exposes the external connection area; wherein, an end face of the protective film formed along a vertical plane including an end face of the sealing substrate, a lower end of the end face of the protective film slants away from the vertical plane in proximity of the boundary between the display area and the external connection area, and the distance D between the lower end of the end face of the protective film and the vertical plane satisfies Mathematical Expression: D≦T·tan θ, where T represents a film thickness of the protective film in the position sufficiently inside from the end face of the sealing substrate, θ represents an angle which is made by a plane which is on the face drawn from an upper end to the lower end of the end face of the protective film, in relation to the vertical plane, and its value is within 0°<θ≦10°.
