Abstract

A method of manufacturing an EL display device having a panel part that comprises a light emitting part in which a plurality of pixels are arrayed, and a thin-film transistor array device to control light emission of the light emitting part. The method includes the following steps: forming the panel part on a substrate, and then forming a sealing layer to cover the panel part. The step of forming the sealing layer is performed by forming a film configuring the sealing layer, with the mask being disposed over base substrate. Mask includes contact part in contact with the base substrate, and edge part disposed over the panel part with a gap between the edge part and the panel part.

Claims (11)

1. A method of manufacturing an EL display device having a panel part, the panel part comprising:

a light emitting part, in which a plurality of pixels are arrayed; and

a thin-film transistor array device to control light emission of the light emitting part,

the method comprising the successive steps of:

forming the panel part on a substrate; and

forming a sealing layer to cover the panel part,

wherein the step of forming the sealing layer is performed by forming a film configuring the sealing layer with a mask being disposed over the substrate; and

the mask includes:

a contact part in contact with the substrate for covering an edge portion of the substrate; and

an end part disposed over the panel part with a gap therebetween for covering an end part of the panel part, and for preventing the end part from contacting with the panel part.

2. The method of manufacturing the EL display device according to claim 1 , wherein the step of forming the sealing layer is performed by a chemical vapor deposition (CVD) method.
