Display device
A cut which penetrates a resin layer is formed in the resin layer such that the cut surrounds a third upper surface. A film is formed such that the film covers the whole resin layer except for a bottom surface of the resin layer inside the cut and at least a portion of the resin layer is exposed outside the cut. The resin layer which is wholly covered with the film is left inside the cut, and the whole resin layer continuously formed with a surface exposed from the film is removed outside the cut. A bump is formed by the resin layer and the film inside the cut, and a shutter and at least a portion of a drive part are formed by the film outside the cut in a state where these parts are floated from a first substrate.
1. A display device comprising:
a first substrate;
a shutter which is formed on the first substrate and a drive part which is connected to the shutter;
a second substrate which is arranged such that the second substrate faces the first substrate in an opposed manner with a distance therebetween;
a bump which is arranged between the first substrate and the second substrate and which holds the distance between the first and second substrates; and
oil which is filled into a space defined between the first substrate and the second substrate, wherein
the bump includes a resin layer which is formed on the first substrate and a film which covers the whole resin layer except for a bottom surface of the resin layer,
the shutter and the drive part are made of the same material as the film, and an uppermost surface of the bump is at a greater height above the first substrate than an upper-most surface of the shutter.
2. The display device according to claim 1 , wherein the film exhibits higher dissolution resistance to the oil than the resin layer does.
3. The display device according to claim 1 , wherein the film includes a semiconductor film and a metal film.
4. The display device according to claim 3 , wherein the semiconductor film is made of amorphous silicon.
5. The display device according to claim 3 , wherein the metal film is made of aluminum.
6. The display device according to claim 1 , wherein the bump faces the second substrate with a predetermined gap therebetween.
7. The display device according to claim 1 , wherein the bump is formed in contact with the second substrate.
8. The display device according to claim 7 , wherein the second substrate includes a light blocking film in which an opening is formed, and
the bump is formed in contact with the light blocking film.
