Provided is a display device, including: a pair of substrates arranged at an interval; oil filled between the pair of substrates; a shutter arranged in the oil; a drive portion, which is arranged in the oil, for driving the shutter in a predetermined direction; and a wall portion provided in the oil and on one of the pair of substrates. The wall portion is positioned adjacent to the shutter in one of the predetermined direction of the shutter and a direction orthogonal to the predetermined direction. The wall portion has a height exceeding a height of the shutter in a thickness direction of the shutter. The wall portion has at least a part positioned lateral to the shutter.

The present application claims priority from Japanese application JP 2011-110513 filed on May 17, 2011, the contents of which are hereby incorporated by reference into this application.
1. Field of the Invention
The present invention relates to a display device.
In the accompanying drawings:
FIG. 1 is a side view of a display device according to an embodiment of the present invention;
FIG. 2 is a plan view of the display device illustrated in FIG. 1;
Hereinafter, embodiments of the present invention are described with reference to the drawings.
FIG. 1 is a side view of a display device according to the embodiment of the present invention. The display device includes a pair of substrates 10 and 12 having light transmissivity (for example, glass substrates). The pair of substrates 10 and 12 are arranged so as to be opposed to each other at an interval (see FIG. 4). FIG. 2 is a plan view of the display device illustrated in FIG. 1. In FIG. 2, the upper substrate 10 is represented by a virtual line to show the inner structure. As illustrated in FIG. 2, a plurality of (large number of) shutters 14 are provided on the lower substrate 12.
FIG. 3 is a plan view of the shutter and a drive portion thereof. The shutter 14 is a plate which is made of an inorganic material such as semiconductor or a metal, and includes a drive aperture 16. Light is allowed to pass through the drive aperture 16, and is blocked at a part other than the drive aperture 16 of the shutter 14. The drive aperture 16 has a shape long in one direction. Note that, as illustrated in FIG. 1, light is supplied from a backlight unit 18 lying under the substrates.
