Shutter panel and display device including the same
View Patent ↗Provided is a shutter panel including a first substrate on which a plurality of electric field forming electrodes are parallel to each other, a second substrate opposed to the first substrate, and a liquid crystal layer disposed on the first and second substrates. Each of the electric field forming electrodes has both side surfaces facing the adjacent electric field forming electrodes, and both side surfaces are provided with protrusion parts protruding toward the adjacent electric field forming electrodes.
1. A shutter panel comprising:
a first substrate on which a plurality of electric field forming electrodes are parallel to each other;
a second substrate opposed to the first substrate; and
a liquid crystal layer disposed on the first and second substrates,
wherein each of the electric field forming electrodes has at least one side surface facing an adjacent electric field forming electrode, and at least one side surface is provided with protrusion parts protruding to the adjacent electric field forming electrode, each of the electric field forming electrodes includes a straight central portion from which the protrusion parts protrude, and a width of the protrusion parts at a line along the straight central portion at a base of the protrusion parts is wider than a width of the protrusion part at an edge of the electric field forming electrode;
wherein one of the electric field forming electrodes has one of the side surfaces provided with a first protrusion part, and the other of the side surfaces provided with a second protrusion part,
wherein the first and second protrusion parts comprise a plurality of protrusions,
wherein a protrusion height of the first protrusion part at an arbitrary position is different from a protrusion height of the second protrusion part at a position corresponding to the arbitrary position,
wherein the first and second protrusion parts have curved surfaces that are not parallel to each other in arbitrary ranges corresponding to each other.
2. The shutter panel of claim 1 , wherein protrusions of the first protrusion part protrude to a boundary with the protrusions of the second protrusion part.
3. The shutter panel of claim 1 , wherein a sum of protrusion heights of the first and second protrusion parts at arbitrary positions corresponding to each other is equal to or greater than half a distance between the neighboring electric field forming electrodes.
4. A display device comprising:
a display panel displaying an image; and
a shutter panel dividing a planar image from the display panel into a left-eye image and a right-eye image,
wherein the shutter panel comprises:
a first substrate on which a plurality of electric field forming electrodes are parallel to each other, the first substrate being disposed on a light emitting side of the display panel;
a second substrate opposed to the first substrate; and
a liquid crystal layer disposed on the first and second substrates,
wherein each of the electric field forming electrodes has at least one of its side surfaces facing an adjacent electric field forming electrode, and the other side surface is provided with protrusion parts protruding to the adjacent electric field forming electrode, and wherein each of the electric field forming electrodes includes a straight central portion from which the protrusion parts protrude, and a width of the protrusion parts from a line along the straight central portion at a base of the protrusion parts is wider than a width of the protrusion parts at an edge of the electric field forming electrode;
wherein one of the electric field forming electrodes has one of the side surfaces provided with a first protrusion part, and the other of the side surfaces provided with a second protrusion part,
wherein a protrusion height of the first protrusion part at an arbitrary position is different from a protrusion height of the second protrusion part at a position corresponding to the arbitrary position,
wherein the first and second protrusion parts have curved surfaces that are not parallel to each other in arbitrary ranges corresponding to each other.
5. The display device of claim 4 , wherein the first and second protrusion part comprise a plurality of protrusions.
6. The display device of claim 5 , wherein protrusions of the first protrusion part protrude to a boundary with the protrusions of the second protrusion part.
