Display device
A display device includes a light emitting unit and a light controlling means. The light controlling means is disposed on a route that a light emitted from the light emitting unit moves. Through the light controlling means, the light is controlled to move at a first angle in a horizontal direction and at a second angle in a vertical direction. The first angle is different from the second angle.
1. A display device, comprising:
a light emitting unit;
a pixel defining layer; and
a light controlling means disposed on a route that a light emitted from the light emitting unit moves, through which the light is controlled to move at a first angle in a horizontal direction and at a second angle in a vertical direction, wherein the light controlling means comprises:
a plurality of first collimating walls arranged in the horizontal direction;
wherein the first angle is different from the second angle;
wherein the light emitting unit and the pixel defining layer are disposed on a same side of the light controlling means, the light emitting unit is between adjacent two of the plurality of first collimating walls, and at least one of the plurality of first collimating walls overlaps the pixel defining layer.
2. The display device according to claim 1 , wherein the first angle is greater than the second angle.
3. The display device according to claim 1 , wherein the light controlling means is a collimator.
4. The display device according to claim 3 , wherein the collimator comprises the plurality of first collimating walls and a plurality of second collimating walls, the plurality of first collimating walls are arranged in the horizontal direction and spaced from each other at a first distance, and the plurality of second collimating walls are arranged in the vertical direction and spaced from each other at a second distance.
5. The display device according to claim 4 , wherein the first distance is greater than the second distance.
