Method for manufacturing display device and display device
A method for manufacturing a display device includes preparing a flexible substrate that includes an alignment mark in a frame area, preparing a spacer that includes a notch or a hole penetrating from a back surface side to a display surface side of the spacer, disposing the spacer on a back surface side of the flexible substrate, and bending the bent area of the flexible substrate to conform to a shape of the spacer and disposing the terminal area of the flexible substrate on the back surface side of the spacer. In the step of disposing the spacer, the alignment mark is read through the notch or the hole from the back surface side of the flexible substrate so as to position the spacer on the flexible substrate.
1. A display device comprising:
a spacer; and
a flexible substrate that includes a display area for displaying an image, a frame area in a periphery of the display area, a bent area disposed outside the frame area and curved to conform to a shape of the spacer, and a terminal area disposed on a back surface side of the spacer through the bent area and provided with a terminal, wherein
the flexible substrate includes an alignment mark, and
the spacer includes a notch or a hole at a position corresponding to the alignment mark, the notch or the hole penetrating from the back surface side to a display surface side of the spacer, wherein
a first reinforcing film is arranged between the back surface side and the flexible substrate,
a second reinforcing film is arranged between the display surface side and the flexible substrate,
the display area, the second reinforcing film, the spacer, the first reinforcing film, and the terminal area are arranged in this order in a cross sectional view,
the notch or the hole has a first portion at the back surface side and a second portion at the display surface side,
the notch or the hole and the alignment mark are arranged outside of the first reinforcing film and the second reinforcing film in a plan view of peripheries of the bent area of the flexible substrate such that the notch or the hole is aligned with the alignment mark in a folded state of the flexible substrate, and
the alignment mark, the first portion, and the second portion are aligned with one another in a plan view.
2. The display device according to claim 1 , wherein
a first bottom surface is provided on the display surface side of the spacer, the first bottom surface being formed because of a first step being formed, and
the first reinforcing film that is disposed on the first bottom surface is provided on the back surface side of the flexible substrate.
3. The display device according to claim 2 , wherein
a second bottom surface is provided on the back surface side of the spacer, the second bottom surface being formed because of a second step being formed, and
the second reinforcing film that is disposed on the second bottom surface is provided on the display surface side of the flexible substrate.
4. The display device according to claim 3 , wherein
the spacer includes a guide section in contact with the bent area, and
the notch or the hole is provided closer to the guide section than the first step and the second step.
5. The display device according to claim 1 , wherein
the alignment mark is formed in the frame area.
