## Abstract

A method of manufacturing an electronic apparatus includes the steps of: providing an electronic panel defining a through hole; providing an electronic module having at least a portion thereof received in the through hole; providing a protective member having a first surface adjacent to the electronic panel, a hole area overlapping the through hole, a peripheral area surrounding the hole area, and a second surface facing the first surface and spaced apart from the electronic module, the providing of the protective member including: providing an unfinished protective member; attaching a film to the peripheral area; and forming a generally concave-convex pattern by contacting an acid solution with the hole area.

## Claims

### Claim 1

An electronic apparatus comprising:
an electronic panel having a through hole;
an electronic module having at least a portion thereof received in the through hole; and
a protective member having a first surface adjacent to the electronic panel, a hole area overlapping the through hole, a peripheral area surrounding the hole area, and a second surface facing the first surface and spaced apart from the electronic module, wherein the hole area comprises a concave-convex pattern, and
wherein the concave-convex pattern overlaps the through hole in a thickness direction.

### Claim 2 (depends on 1)

The electronic apparatus of claim 1, wherein the protective member has a thickness (D1) and the concave-convex pattern has a height (H1) that satisfy the following Equation: 0.71×10−5≤H1/D1≤3×10−5.

### Claim 3 (depends on 1)

The electronic apparatus of claim 1, wherein the hole area has an average surface roughness greater than an average surface roughness of the peripheral area.

### Claim 4 (depends on 1)

The electronic apparatus of claim 1, wherein the electronic module comprises a camera module and the protective member comprises a window.

### Claim 5 (depends on 1)

The electronic apparatus of claim 1, further comprising an adhesive layer disposed between the protective member and the electronic panel with the adhesive layer defining an opening therethrough that overlaps the through hole.

### Claim 6

An electronic apparatus comprising:
an electronic panel having a through hole;
an electronic module having at least a portion thereof received in the through hole; and
a protective member having a first surface adjacent to the electronic panel, a hole area overlapping the through hole, a peripheral area surrounding the hole area, and a second surface facing the first surface and spaced apart from the electronic module, wherein the hole area comprises a concave-convex pattern, wherein the concave-convex pattern comprises a plurality of concave portions recessed toward the second surface, with at least some of the concave portions having a truncated cone shape or a hemispherical shape.

### Claim 7

An electronic apparatus comprising:
an electronic panel having a through hole;
an electronic module having at least a portion thereof received in the through hole; and
a protective member having a first surface adjacent to the electronic panel, a hole area overlapping the through hole, a peripheral area surrounding the hole area, and a second surface facing the first surface and spaced apart from the electronic module, wherein the hole area comprises a concave-convex pattern, wherein the concave-convex pattern has a height equal to or greater than about 5 nm and equal to or smaller than about 15 nm in a thickness direction of the protective member.
