Embodiment approach

[0053] [1. Configuration of display device]

[0054] refer to figure 1 as well as figure 2 , a display device including the display panel according to this embodiment will be described.

[0055] figure 1 It is a schematic diagram showing a display device 90 including the display panel 1 according to the embodiment. figure 2 is a block diagram showing the configuration of the display device 90 .

[0056] The display device 90 includes a flexible display panel 1 and a control unit 95 that controls the drive of the display panel 1 .

[0057] The display panel 1 is composed of a plurality of pixels arranged in a two-dimensional matrix. In a display panel for color display, for example, three sub-pixels are formed by three EL (Electro Luminescence: electroluminescence) elements corresponding to the colors of RGB (red, green, blue), and by combining the three sub-pixels, to form a pixel. In addition, each pixel is not limited to three sub-pixels, and may be formed of one su...

Abstract

The impact resistance of a display panel is improved. The display panel (1A) is a display panel that is flexible, including: an EL structure layer (10) including a plurality of EL elements arranged two-dimensionally; a foamed resin layer (60) on a side of the EL structure layer (10) that is opposite to a light emitting surface (10a) of the EL structure layer (10); a metal layer (50) provided between the EL structure layer (10) and the foamed resin layer (60); and a first adhesive layer (20) provided between the EL structure layer (10) and the metal layer (50) and comprises an adhesive having an elastic modulus of 90 kPa or more.

Description

technical field [0001] The present disclosure relates to a flexible display panel and a display device including the display panel. Background technique [0002] As a display panel used in a display device such as a digital television or a digital signage, there is a known flexible display panel capable of bending. Although the flexible display panel has the characteristics of being thin, light and soft, it also has the characteristics of being weak against external impact. [0003] As an example of such a display panel, Patent Document 1 discloses a display panel in which protective sheets are provided on both sides of the panel. Since the display panel is provided with a protective sheet, it can not only suppress the occurrence of cracks, but also absorb external impact. [0004] (Prior art literature) [0005] (patent documents) [0006] Patent Document 1 Japanese Unexamined Patent Application Publication No. 2020-21091 [0007] For example, when the display panel is...
