Abstract
According to one embodiment, a method of manufacturing a display device includes placing a transparent substrate having a first main surface, placing a transparent material above the first main surface, forming a transparent layer, in which at least a part of the first main surface is exposed, by patterning the transparent material thus placed, placing a low-refractive-index material on the first main surface and the transparent layer, and forming a low-refractive index layer to which the transparent layer is exposed, by patterning the low-refractive index material thus placed. The transparent layer has an oil repellency higher than that of the first main surface with respect to the low-refractive index layer.

A method of manufacturing a display device having a liquid crystal layer containing a polymer-dispersed liquid crystal, which can switch between a state in which light entering the liquid crystal layer is transmitted and a state in which the light is scattered according to an applied voltage, the method comprising:
- placing a transparent substrate having a first main surface;
- placing a transparent material above the first main surface;
- forming a transparent layer, in which at least a part of the first main surface is exposed, by patterning the transparent material thus placed;
- placing a low-refractive-index material on the first main surface and the transparent layer;
- and
- forming a low-refractive index layer to which the transparent layer is exposed, by patterning the low-refractive index material thus placed,
- wherein
- the low-refractive index layer has a refractive index lower than that of the transparent substrate, and
- the transparent layer has an oil repellency higher than that of the first main surface with respect to the low-refractive index layer.
A method of manufacturing a display device having a liquid crystal layer containing a polymer-dispersed liquid crystal, which can switch between a state in which light entering the liquid crystal layer is transmitted and a state in which the light is scattered according to an applied voltage, the method comprising:

- forming a common electrode having a third main surface on the second main surface;
- placing a transparent material on the third main surface;
- forming a transparent layer, in which at least a part of the third main surface is exposed, by patterning the transparent material thus placed;
- placing a low-refractive-index material on the third main surface and the transparent layer;
- and
- forming a low-refractive index layer to which the transparent layer is exposed, by patterning the low-refractive index material thus placed,
- wherein
- the low-refractive index layer has a refractive index lower than that of the transparent substrate, and the transparent layer has an oil repellency higher than that of the third main surface with respect to the low-refractive index layer.
A display device comprising:
- a first transparent substrate;
- a second transparent substrate;
- a liquid crystal layer containing a polymer-dispersed liquid crystal and disposed between the first transparent substrate and the second transparent substrate;
- and
- a low-refractive index layer disposed between the liquid crystal layer and the second transparent substrate and having a refractive index lower than that of the second transparent substrate,
- wherein
- the low-refractive index layer has a bottom portion located on a side of the second transparent substrate and an upper portion having a width greater than that of the bottom portion.
