Abstract

A display device including: a display unit including a plurality of pixels; and a color converter overlapping the display unit. The color converter includes a first color converter, a second color converter, a transmitter, and a light blocking member. The first color converter includes a first color converting layer including first semiconductor nanocrystals, and a first color filter overlapping the first color converting layer. The second color converter includes a second color converting layer including second semiconductor nanocrystal, and a second color filter overlapping the second color converting layer, the transmitter includes a transmitting layer. The light blocking member includes a light blocking member disposed among the adjacent first color converting layer, the second color converting layer, and the transmitting layer, a metal layer disposed on the light blocking member, and a liquid repellent cover layer overlapping the metal layer.

Claims (31)

1 . A display device comprising:

a display unit including a plurality of pixels; and

a color converter overlapping the display unit,

wherein:

the color converter includes a first color converter, a second color converter, a transmitter, and a light blocking member,

the first color converter includes:

a first color converting layer including first semiconductor nanocrystals; and

a first color filter overlapping the first color converting layer;

the second color converter includes:

a second color converting layer including second semiconductor nanocrystal; and

a second color filter overlapping the second color converting layer;

the transmitter includes a transmitting layer;

the light blocking member includes:

a light blocking member disposed among the adjacent first color converting layer, the second color converting layer, and the transmitting layer;

a metal layer disposed on the light blocking member; and

a liquid repellent cover layer overlapping the metal layer, configured to prevent ink migration; and the liquid repellent cover layer comprises a photosensitive polymer layer; wherein the liquid repellent cover layer is transparent so that it at least partially transmits light; wherein:

the transmitter further includes a third color filter overlapping the transmitting layer; and

at least two of the first color filter, the second color filter, and the third color filter overlap each other on the light blocking member.

2 . The display device of claim 1 , wherein the metal layer covers a lateral side and a side of the light blocking member.

3 . The display device of claim 1 , wherein the metal layer includes at least one of aluminum (Al) and silver (Ag).

4 . The display device of claim 2 , wherein the liquid repellent cover layer overlaps a side of the light blocking member.

5 . The display device of claim 4 , wherein the liquid repellent cover layer overlaps the lateral side of the light blocking member.

6 . The display device of claim 1 , wherein the metal layer and the liquid repellent cover layer overlap at least two of the first color filter, the second color filter, and the third color filter overlapping the light blocking member.

7 . The display device of claim 1 , wherein the display unit includes:

a first substrate;

a transistor disposed on the first substrate;

a first electrode electrically connected to the transistor;

a pixel defining layer overlapping at least a portion of the first electrode;

an emission layer disposed on the first electrode; and

a second electrode disposed on the emission layer.

8 . The display device of claim 7 , wherein the pixel defining layer overlaps the light blocking member.
