Problems solved by technology

[0003] In this organic EL display panel, organic substances are used for the luminescent material of each pixel, etc., and since the organic material contains moisture, its life will be shortened, so it is necessary to reduce the moisture existing in the space of each pixel as much as possible.

Embodiment Construction

[0067] Hereinafter, embodiments of the present invention will be described based on the drawings.

[0068]Figures 1 and 2 show embodiments of substrate bonding. In this embodiment, an EL substrate 10 serving as a pixel substrate forming a pixel and a package substrate 12 for sealing the upper surface of the EL substrate 10 are arranged facing each other. Furthermore, the packaging substrate 12 is located at the part to be welded and packaged, and has an absorber such as opaque glass for absorbing laser light. For example, the packaging substrate 12 is formed opaque by doping metal by ion implantation or ion exchange, and the opaque region 14 serving as an absorber region for absorbing laser light is formed. Here, the ion exchange method is to form a patterned photoresist on the packaging substrate 12 and dip it in a solution containing a predetermined metal to exchange ions (such as sodium) in the packaging substrate 12 to diffuse the metal in the packaging substrate 12. The...

Abstract

The present invention provides a method for manufacturing a display panel and a display panel. The purpose of the display panel is to ensure that the package is made into a top emission type. Opposite configuration; for the packaging substrate (12), an opaque area (14) is formed in the peripheral part in advance to become a square frame shape. Laser light is irradiated to the opaque area (14) through the EL substrate (10), and the portion is heated to make the glass bulge and weld. In addition, since the encapsulation substrate (12) is still transparent except for the opaque region (14), it can be made into a top emission type.

Description

technical field [0001] The present invention relates to the manufacture of display panels such as organic electroluminescence (EL) display panels, and in particular to the packaging structure of the display panels. Background technique [0002] Plasma Display Panel (PDP), Liquid Crystal Display (Liquid Crystal Display, LCD) and the like have been popularized as thin flat panel display panels, and organic EL display panels have also been put into practical use. [0003] In this organic EL display panel, organic substances are used for the luminescent material of each pixel, and since the organic material contains moisture, its life will be shortened. Therefore, it is necessary to reduce the moisture present in the space of each pixel as much as possible. Therefore, the EL substrate formed in a matrix corresponding to the display pixels containing the EL element is opposed to the packaging substrate with a predetermined interval, and the peripheral parts of these substrates ar...
