Abstract

The present invention provides a method for manufacturing a display panel, comprising the following steps: a step of forming a substrate (60) for a display device, wherein a first substrate ( 20), a plurality of organic electroluminescent elements (40) each having the same configuration as the connection electrodes each having the connection terminal (46) formed thereon are arranged in a manner overlapping with the plurality of color filter elements, The process of forming a substrate (60) for a display device in this way; the process of preparing a substrate (50) for driving, which is equipped with a driving circuit for driving a plurality of organic electroluminescence elements, and is connected to the driving circuit. Connecting portion (52a) connected to it; the process of arranging a bonding member (74X) on the surface of the substrate for display device or the substrate for driving, so that in the state where the substrate for display device and the substrate for driving are bonded, the bonding member Surrounding a plurality of organic electroluminescence elements; the process of laminating the display device substrate and the driving substrate in such a way that the connection terminal and the connection part are in contact.

Description

technical field [0001] The present invention relates to a method of manufacturing a display panel including a plurality of organic electroluminescence (electroluminescence) elements (hereinafter also referred to as organic EL elements), a substrate for a display device used in the manufacturing method, and a display device comprising the same. A display panel using a substrate, and a display device including the display panel. Background technique [0002] Development of a flat-panel display (hereinafter sometimes referred to as "organic EL display device" or simply "display device") in which a self-luminous organic EL element is used as a light source for pixels is in progress. In an organic EL display device, a display panel that emits three colors of red, green, and blue light is installed, and the three colors of light are superimposed at a predetermined light intensity ratio, thereby enabling color display. [0003] In the case of a display panel for color display, thr...
