Abstract

A display device includes a flexible substrate including a first region including a display region, a second region including a curved region, and a third region including a terminal region; an electro-optical element located in the display region; and a resin layer continuously extending from the first region to the third region.

Claims (14)

1. A display device, comprising:

a flexible substrate including a first region including a display region, a second region including a curved region, and a third region including a terminal region, the flexible substrate having a first surface and a second surface opposite to the first surface;

an organic EL element located in the display region;

a resin layer provided on the first surface of the flexible substrate, and continuously extending from the first region to the third region, the resin layer being located on the organic EL element in the display region;

a first protective film provided on the resin layer;

a polarizing member on the first protective film, the polarizing member being smaller than the first protective film,

at least two second protective films, wherein one of the second protective films is provided on the second surface of the first region and other one of the second protective films is provided on the second surface of the third region, and

a spacer located between the first region and the third region, the spacer having a curved portion being in contact with the flexible substrate at the second region and conformed to the shape of the second region,

wherein

the resin layer is an adhesive bonding the first protective film to the organic EL element and thicker than the flexible substrate, and has a first portion having a high degree of polymerization in the curved region and a second portion in the display region having a lower degree of polymerization than the first portion,

a border between the first portion and the second portion is in the first region and inner to an end of the first protective film, and

an edge of the first protective film extending along and adjacent to the second region is arranged in the first region in a cross-sectional view.

2. The display device according to claim 1 , wherein in the first region, the resin layer is provided on another resin layer provided on the organic EL element.

3. The display device according to claim 1 , wherein the resin layer covers the curved region.
