## Abstract

A display apparatus includes a substrate. A light-emitting element is disposed on the substrate. The light-emitting element emits light. A photodetector is disposed on the substrate. The photodetector detects light. A light-blocking layer includes a first hole and a second hole. The first hole is disposed above the light-emitting element. The second hole is disposed above the photodetector. A first color filter is disposed to cover the first hole. A second color filter is disposed to cover the second hole. A third color filter is arranged to overlap a portion of the second hole.

## Claims

### Claim 1

An electronic device, comprising:
a display apparatus comprising:
a substrate;
a light-emitting element disposed on the substrate, the light-emitting element emits light;
a photodetector disposed on the substrate, the photodetector detecting light;
a light-blocking layer including a first hole and a second hole, the first hole is disposed above the light-emitting element, and the second hole is disposed above the photodetector;
a first color filter disposed to cover the first hole;
a second color filter disposed to cover the second hole; and
a third color filter arranged to overlap a portion of the second hole, the third color filter reducing a resolution distance of light reaching the photodetector.

### Claim 2 (depends on 1)

The electronic device of claim 1, wherein:
the third color filter is a blue color filter transmitting blue light; and
the first color filter is a green color filter transmitting green light, or a red color filter transmitting red light.

### Claim 3 (depends on 1)

The electronic device of claim 1, wherein the second color filter transmits light of a same color as a color of the first color filter.

### Claim 4 (depends on 1)

The electronic device of claim 1, wherein at least a portion of the third color filter is disposed on the second color filter.

### Claim 5 (depends on 4)

The electronic device of claim 4, wherein the third color filter is connected to a first surface of the second color filter that faces a direction that the light is emitted.

### Claim 6 (depends on 1)

The electronic device of claim 1, wherein at least a portion of the third color filter is disposed under the second color filter.

### Claim 7 (depends on 6)

The electronic device of claim 6, wherein the third color filter is connected to a first surface of the light-blocking layer that faces the substrate.

### Claim 8 (depends on 1)

The electronic device of claim 1, wherein at least a portion of the third color filter is disposed between the light-blocking layer and the second color filter.

### Claim 9 (depends on 8)

The electronic device of claim 8, wherein the third color filter is connected to a second surface of the light-blocking layer that forms an inner surface of the second hole.

### Claim 10 (depends on 8)

The electronic device of claim 8, wherein the third color filter is connected to a third surface of the light-blocking layer that faces a direction that the light is emitted.

### Claim 11

A method of manufacturing a display apparatus, the method comprising:
disposing a light-emitting element on a substrate, the light-emitting element emitting light;
disposing a photodetector on the substrate, the photodetector detecting light;
disposing a light-blocking layer including a first hole and a second hole, the first hole is disposed above the light-emitting element, and the second hole is disposed above the photodetector;
disposing a first color filter to cover the first hole;
disposing a second color filter to cover the second hole; and
disposing a third color filter, the third color filter overlaps a portion of the second hole, the third color filter reducing a resolution distance of light reaching the photodetector.

### Claim 12 (depends on 11)

The method of claim 11, wherein the disposing of the third color filter includes, after the disposing of the second color filter, disposing at least a portion of the third color filter on the second color filter.

### Claim 13 (depends on 12)

The method of claim 12, wherein the third color filter is connected to a first surface of the second color filter that faces a direction that the light is emitted.

### Claim 14 (depends on 11)

The method of claim 11, wherein the disposing of the light-blocking layer includes, after the disposing of the third color filter, disposing at least a portion of the light-blocking layer on the third color filter.

### Claim 15 (depends on 14)

The method of claim 14, wherein the third color filter is connected to a first surface of the light-blocking layer that faces the substrate.

### Claim 16 (depends on 11)

The method of claim 11, wherein:
the disposing of the third color filter includes, after the disposing of the light-blocking layer,
disposing the third color filter on the light-blocking layer; and
the disposing of the second color filter includes, after the disposing of the third color filter, disposing at least a portion of the second color filter on the third color filter.

### Claim 17 (depends on 16)

The method of claim 16, wherein the third color filter is connected to a second surface of the light-blocking layer that forms an inner surface of the second hole.

### Claim 18 (depends on 16)

The method of claim 16, wherein the third color filter is connected to a third surface of the light-blocking layer that faces a direction that the light is emitted.

### Claim 19 (depends on 11)

The method of claim 11, wherein:
the third color filter is a blue color filter transmitting blue light; and
the first color filter is a green color filter transmitting green light, or a red color filter transmitting red light.

### Claim 20 (depends on 11)

The method of claim 11, wherein the second color filter transmits light of a same color as a color of the first color filter.
