Abstract

According to one embodiment, a display device includes an insulating substrate, a light-shielding member disposed above the insulating substrate, a first color filter disposed above the insulating substrate, a second color filter disposed alongside the first color filter, a partition disposed on the light-shielding member and between the first color filter and the second color filter and an insulating film disposed on the first color filter and the second color filter, and an upper surface of the partition and an upper surface of the insulating film are located on a same plane.

Claims (57)

1. A display device comprising:

an insulating substrate;

a switching element disposed on the insulating substrate and connected to a signal line;

a relay electrode connected to the switching element;

a first color filter disposed above the insulating substrate;

a second color filter disposed alongside the first color filter;

a partition disposed on the signal line and between the first color filter and the second color filter;

an insulating film disposed on the first color filter and the second color filter;

a first transparent electrode disposed on the insulating film;

an interlayer insulating film disposed on the first transparent electrode; and

a second transparent electrode disposed on the interlayer insulating film, wherein

an upper surface of the partition and an upper surface of the insulating film are located on a same plane, and

the insulating film is in contact with the relay electrode and comprises a contact hole penetrating to the relay electrode.

2. The display device of claim 1 , wherein

an edge of the partition overlaps an edge of the signal line in plan view.

3. The display device of claim 1 , wherein

the partition is formed from a transparent organic material.

4. The display device of claim 1 , wherein

the partition is formed from an organic material containing a black pigment.

5. The display device of claim 1 , wherein

the first transparent electrode is electrically connected to the relay electrode via the contact hole.

6. The display device of claim 1 , wherein

the second transparent electrode is electrically connected to the relay electrode via the contact hole.

7. A display device comprising:

an insulating substrate;

a switching element disposed on the insulating substrate and connected to a signal line;

a relay electrode connected to the switching element;

an island portion disposed on the relay electrode;

a first color filter disposed above the insulating substrate;

a second color filter disposed alongside the first color filter;

a partition disposed on the signal line and between the first color filter and the second color filter;

an insulating film disposed on the first color filter and the second color filter;

a first transparent electrode disposed on the insulating film;

an interlayer insulating film disposed on the first transparent electrode; and

a second transparent electrode disposed on the interlayer insulating film,

wherein

the island portion comprises a contact hole penetrating to the relay electrode.

8. The display device of claim 7 , wherein

the island portion and the partition have a same height.

9. The display device of claim 7 , wherein

the partition and the island portion are formed from a same material.

10. A display device comprising:

an insulating substrate;

a switching element disposed on the insulating substrate and connected to a signal line; and

a relay electrode connected to the switching element;

a first color filter disposed above the insulating substrate;

a second color filter disposed alongside the first color filter; and

a partition disposed on the signal line and between the first color filter and the second color filter;

a first transparent electrode in contact with upper surfaces of the first and second color filters:

an interlayer insulating film disposed on the first transparent electrode; and

a second transparent electrode disposed on the interlayer insulating film, wherein

an upper surface of the partition and the upper surfaces of the first and second color filters are located on a same plane, and

the second color filter comprises a contact hole penetrating to the relay electrode.

11. The display device of claim 10 , wherein

the first transparent electrode is electrically connected to the relay electrode via the contact hole.

12. The display device of claim 10 , wherein

the second transparent electrode is electrically connected to the relay electrode via the contact hole.
