Abstract
A manufacturing method of a display device includes locating a base member on a support substrate; and removing a part of the support substrate by preventing a first surface portion having a predetermined region in a border plane between the support substrate and the base member from being irradiated with laser light through the support substrate, whereas irradiating a second surface portion, other than the predetermined region, in the border plane between the support substrate and the base member with the laser light through the support substrate.

A manufacturing method of a display device, comprising:
- locating a base member on a support substrate;
- and
- removing a part of the support substrate by preventing a first surface portion having a predetermined region in a border plane between the support substrate and the base member from being irradiated with laser light through the support substrate, whereas irradiating a second surface portion, other than the predetermined region, in the border plane between the support substrate and the base member with the laser light through the support substrate.
A display device, comprising:
- a base member support portion formed of any of glass, a ceramic material and quartz;
- and
- a base member including a first flat portion covering a top surface the base member support portion, a U-shaped portion extending from the first flat portion, the U-shaped portion having a U-shaped cross-section, and a second flat portion extending from the U-shaped portion, the second flat portion covering a bottom surface of the base member support portion and being larger than the base member support portion.
A display device, comprising:
- a base member support portion;
- and
- a base member including a first flat portion covering a top surface the base member support portion, a U-shaped portion extending from the first flat portion, the U-shaped portion having a U-shaped cross-section, and a second flat portion extending from the U-shaped portion, the second flat portion covering a bottom surface of the base member support portion and being larger than the base member support portion;
- wherein the first flat portion has a first surface facing the base member support portion,
- the U-shaped portion and the second flat portion has a second surface facing the base member support portion, and
- a roughness of the second surface is larger than a roughness of the first surface.
