## Abstract

A substrate for a display apparatus is providing 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; a second translucent resin layer disposed on the light shielding layer; and an orientation film disposed on the second translucent resin layer, wherein the first translucent resin layer includes a frame region part that is in contact with the first substrate in a part of a frame region arranged around a display region in which light is transmitted through the translucent coloring layer, and the frame region part of the first translucent resin layer extends along one side of the first substrate.

## Claims

### Claim 1

A substrate for a display apparatus 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 that is a matrix of light shielding parts and disposed on the first translucent resin layer;
a second translucent resin layer disposed on the light shielding layer; and
an orientation film disposed on the second translucent resin layer,
wherein
the first translucent resin layer includes a frame region part that is in contact with the first substrate in a part of a frame region arranged around a display region in which light is transmitted through the translucent coloring layer, and
the frame region part of the first translucent resin layer extends along one side of the first substrate.

### Claim 2 (depends on 1)

The substrate for a display apparatus according to claim 1, wherein an area of the first translucent resin layer is identical to an area of the first substrate when viewed in a first direction perpendicular to the first substrate.

### Claim 3 (depends on 1)

The substrate for a display apparatus 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 4 (depends on 3)

The substrate for a display apparatus according to claim 3, wherein the spacer is made of a material identical to that of the second translucent resin layer, and is integrated with the second translucent resin layer.

### Claim 5 (depends on 1)

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

### Claim 6

A display apparatus comprising:
a substrate for a display apparatus that includes a first substrate;
a second substrate that overlaps the first substrate; and
a liquid crystal layer arranged between the substrate for a display apparatus and the second substrate,
wherein
the substrate for a display apparatus further includes:
a translucent coloring layer disposed on the first substrate;
a first translucent resin layer disposed on the translucent coloring layer;
a light shielding layer that is a matrix of light shielding parts and disposed on the first translucent resin layer;
a second translucent resin layer disposed on the light shielding layer; and
an orientation film disposed on the second translucent resin layer,
wherein
the first translucent resin layer includes a frame region part that is in contact with the first substrate in a part of a frame region arranged around a display region in which light is transmitted through the translucent coloring layer, and
the frame region part of the first translucent resin layer extends along one side of the first substrate.

### Claim 7 (depends on 1)

The substrate for a display apparatus according to claim 1, wherein
the frame region part of the first translucent resin layer is disposed without overlapping the translucent coloring layer and the light shielding layer, when viewed in a first direction perpendicular to the first substrate.
