Method of manufacturing a display device

1. A method of manufacturing a display device that includes a structure that is formed so as to have a protrusion at least in a normal direction of a first substrate, and an electrode that is formed on a side wall surface of the structure, the method comprising:

forming a transparent conductive which becomes the electrode;

forming a low-affinity material having a lower affinity for a resist film than the structure, on an upper surface of the transparent conductive film above a top surface of the protrusion of the structure;

forming the resist film by applying a liquid resist material to the transparent conductive film and then fixing the resist material;

forming an opening that exposes the transparent conductive film in the resist film by removing the low-affinity material;

etching the transparent conductive film which is a lower layer using the resist film as a protective film; and

removing the resist film.

2. The method according to claim 1 ,

wherein the structure includes a first structure that is formed at least in a pixel boundary portion in a long-side direction to have a protrusion,

wherein the electrode includes a first electrode formed of a pair of first wall-shaped electrodes that are formed on a side wall surface of the first structure, and a second electrode that is formed in a pixel display area interposed between the pair of first wall-shaped electrodes and formed along an extension direction of the first electrode, and

wherein an application location of the low-affinity material includes at least a top surface of the protrusion of the first structure.

3. The method according to claim 1 ,

wherein the structure includes first structures each of which is formed at least in the pixel boundary portion in a long-side direction, and a second structure that is formed in the pixel display area interposed between the first structures and formed to have a protrusion at least along an extension direction of the first structures,

wherein the electrode includes a first electrode formed of a pair of first wall-shaped electrodes that are formed on the side wall surface of the first structure, and a second wall-shaped electrode that is formed so as to cover a head surface and a side wall surface of the second structure, and

wherein the application location of the low-affinity material includes at least a top surface of the protrusion of the second structure.

4. The method according to claim 3 ,

wherein the first electrode includes a flat electrode that extends to the pixel display area from a lower end of the first wall-shaped electrode, and the second wall-shaped electrode that extends from an end of the flat electrode so as to be formed on the side wall surface of the second structure and that are disposed so as to overlap with the second electrode with an insulating film interposed therebetween.

5. The method according to claim 3 ,

wherein the second structure has a protrusion amount from the first substrate which is smaller than the first structure.

6. The method according to claim 1 ,

wherein the application of the low-affinity material includes applying the low-affinity material to a predetermined location using a transfer method that attaches the low-affinity material to a film surface and transfers the low-affinity material attached to the film surface to the surface of the first substrate.

7. The method according to claim 1 ,

wherein the application of the low-affinity material includes applying the low-affinity material to a predetermined location using an inkjet printing method that directly prints a liquid low-affinity material to the surface of the first substrate.

8. A method of manufacturing a display device that includes a structure that is formed so as to have a protrusion at least in a normal direction of a first substrate, and an electrode that is formed on a side wall surface of the structure, the method comprising:

forming a low-affinity material on a top surface of the protrusion of the structure, the low-affinity material having lower affinity than the structure for a transparent conductive film which becomes the electrode;

depositing a material for the transparent conductive film on an upper surface of the first substrate; and

removing the low-affinity material on the top surface of the protrusion of the structure.

9. The method according to claim 8 ,

wherein the transparent conductive film is formed by applying a liquid transparent conductive film material to the upper surface of the first substrate.
