LIGHT EMITTING DEVICE
A light emitting device is provided and includes a first substrate, a light blocking element disposed on the first substrate, and a plurality of light emitting diodes. The light blocking element has a first opening, a second opening, and a third opening, wherein the first opening is adjacent to the second opening, the third opening is adjacent to the first opening, and the first opening and the second opening have different areas. One of the light emitting diodes is overlapped with the third opening. The first opening and the second opening are not overlapped with the plurality of light emitting diodes in a normal direction of a surface of the first substrate.
1 . A light emitting device, comprising:
a first substrate;
a light blocking element disposed on the first substrate, wherein the light blocking element has a first opening, a second opening, and a third opening, wherein the first opening is adjacent to the second opening, the third opening is adjacent to the first opening, and the first opening and the second opening have different areas; and
a plurality of light emitting diodes, wherein one of the plurality of light emitting diodes is overlapped with the third opening,
wherein the first opening and the second opening are not overlapped with the plurality of light emitting diodes in a normal direction of a surface of the first substrate.
2 . The light emitting device as claimed in claim 1 , wherein an area of the third opening is less than an area of the second opening.
3 . The light emitting device as claimed in claim 1 , further comprising a color filter overlapped with the third opening.
4 . The light emitting device as claimed in claim 1 , wherein the light blocking element comprises a black photoresist material or a black ink material.
5 . The light emitting device as claimed in claim 1 , wherein an angle formed between two adjacent sides of the first opening or between extending lines of the two adjacent sides of the first opening is greater than 90 degrees.
6 . The light emitting device as claimed in claim 1 , wherein sides of the first opening form a plurality of angles greater than 90 degrees, and a number of the plurality of angles is greater than or equal to 4.
7 . The light emitting device as claimed in claim 1 , further comprising a second substrate opposite to the first substrate, wherein the light blocking element and the plurality of light emitting diodes are disposed between the first substrate and the second substrate.
8 . The light emitting device as claimed in claim 1 , wherein the light blocking element further has a fourth opening adjacent to the second opening, and an area of the fourth opening is the same as an area of the third opening.
