Organic EL film, organic EL display and organic EL illumination

Abstract

The present invention provides a film, which solves the problem, and has excellent adhesion suitability and excellent processing suitability when the film is used as organic EL display devices and isused for organic EL illumination. According to the present invention, the film is arranged on the organic EL non-light-emitting surface side in organic EL display devices and organic EL illumination,the thickness of the film is more than 5 [mu]m and is less than 300 [mu]m, and the MD direction thermal shrinkage Hm in the film length direction and the TD direction thermal shrinkage Ht in the widthdirection of the film being subjected to heat treatment for 30 min at a temperature of 150 DEG C meet the following formulas [1] and [2], wherein the formula [1] is that |Hm| is more than or equal to0 and is less than or equal to 0.7, and the formula [2] is that |Ht| is more than or equal to 0 and is less than or equal to 0.7.

Description

technical field

[0001] The invention relates to an organic EL display and a film for organic EL lighting. Background technique

[0002] With the advancement of electrical and electronic equipment brought about by the development of electronic technology in recent years, the performance, multi-function, miniaturization, and weight reduction of electrical and electronic equipment, the materials of these equipment are also being converted from metal materials and glass materials to plastic materials. Even among plastic materials, a shift to light-weight and flexible plastic films is remarkably ongoing.

[0003] In recent years, thin displays using liquid crystals, organic electroluminescence (organic EL), field emission, and electrophoresis, etc., are increasingly attracting attention. Among them, a display in which the display itself can be bent is called a flexible display. Among flexible displays, organic EL displays, which are currently receiving the most attention, are e...
