Abstract

A fixed aperture includes a first fixed slit and a second fixed slit which are arranged respectively in regions positioned on both sides with a moving line sandwiched therebetween. A drive aperture includes a first drive slit and a second drive slit which are arranged on both sides with the moving line sandwiched therebetween. The first fixed slit and the first drive slit are formed in an extending manner along a first line, and are arranged such that these slits communicate with each other when a shutter is at a position where the transmission of light is allowed. The second fixed slit and the second drive slit are formed in an extending manner along a second line which intersects with the first line, and are arranged such that these slits communicate with each other when the shutter is at a position where the transmission of light is allowed.

Dependent claims

A display device comprising:

a light blocking film in which a fixed aperture which allows the transmission of light is formed;
a shutter which has a drive aperture and controls the transmission of light and the interruption of the transmission of the light;
and
a drive part which moves the shutter and the drive aperture along a moving line which extends in a predetermined direction, wherein
the fixed aperture includes at least a fixed slit which extends in a direction which differs from the predetermined direction and also differs from a direction orthogonal to the predetermined direction, and
the drive aperture includes at least a drive slit which extends in the direction that the fixed slit extends.

3 more elements

A display device comprising:

a pair of substrates which is arranged to face each other;
a light blocking film in which a fixed aperture which allows the transmission of light is formed;
a shutter which has a drive aperture and controls the transmission of the light and the interruption of the transmission of the light;
and
a drive part which moves the shutter and the drive aperture along a moving line which is the predetermined direction, wherein
the drive part is formed on one substrate out of the pair of substrates,
the drive part includes a pair of first electrodes which supports the shutter in a spaced-apart manner from said one substrate with a predetermined distance, and a pair of second electrodes which respectively faces the pair of first electrodes at positions on a side opposite to a shutter side of the pair of first electrodes,
each one of the pair of first electrodes is arranged on both sides of the shutter along the moving line,
the shutter is moved by a potential difference between the first electrode and the second electrode which face each other in an opposed manner,
the pair of first electrodes is arranged so as to have portions which are respectively arranged adjacent to a diagonal of a minimum quadrangular shape which circumscribes a planar profile of the shutter,
said each first electrode includes a pair of first beams which is arranged so as to have portions arranged adjacent to two sides which sandwich one of diagonals,
said each second electrode has a pair of second beams which is arranged so as to have portions arranged adjacent to the pair of first beams, and
said one first beam and said one second beam face each other in an opposed manner.
