## Abstract

A display device is provided and includes a first substrate; a translucent coloring layer disposed on the first substrate; a first translucent resin layer disposed on the translucent coloring layer; a light shielding layer disposed on the first translucent resin layer; and a second translucent resin layer disposed on the light shielding layer, wherein the light shielding layer is a matrix of light shielding parts in a display region, a frame region arranged around the display region, a part of the first translucent resin layer in the frame region part is in direct contact with the first substrate, and the part of the first translucent resin layer in the frame region extends along one side of the first substrate.

## Claims

### Claim 1

A display device comprising:
a first substrate;
a translucent coloring layer disposed on the first substrate;
a first translucent resin layer disposed on the translucent coloring layer;
a light shielding layer disposed on the first translucent resin layer; and
a second translucent resin layer disposed on the light shielding layer,
wherein
the light shielding layer is a matrix of light shielding parts in a display region,
a frame region arranged around the display region,
a part of the first translucent resin layer in the frame region part is in direct contact with the first substrate, and
the part of the first translucent resin layer in the frame region extends along one side of the first substrate.

### Claim 2 (depends on 1)

The display device according to claim 1, further comprising:
a spacer that is disposed to overlap the light shielding layer when viewed in a first direction perpendicular to the first substrate.

### Claim 3 (depends on 2)

The display device according to claim 2, wherein the spacer is made of a material identical to that of the second translucent resin layer.

### Claim 4 (depends on 3)

The display device according to claim 3, wherein the spacer is integrated with the second translucent resin layer.

### Claim 5 (depends on 1)

The display device according to claim 1, wherein the light shielding layer is a single layer when viewed in a first direction perpendicular to the first substrate.

### Claim 6 (depends on 1)

The display device according to claim 1, wherein
the first translucent resin layer overlaps an entire area of the translucent coloring layer and an entire area of the light shielding layer, when viewed in a first direction perpendicular to the first substrate.
