Abstract

A window member including a base substrate and a light shielding layer including a first light shielding pattern disposed in a first area of the base substrate and a second light shielding pattern disposed in a second area of the base substrate while being spaced apart from the first light shielding pattern and providing a signal transmission area at an inner side thereof. The second light shielding pattern includes an edge having a plurality of curved portions on a plane. This arrangement reduces an area of the light shielding pattern adjacent to the signal transmission area of the window member.

First claim

What is claimed is:

1 . A window member comprising:
a base substrate; and a light shielding layer comprising a first light shielding pattern disposed in a first area of the base substrate and a second light shielding pattern disposed in a second area of the base substrate while being spaced apart from the first light shielding pattern and providing a signal transmission area at an inner side thereof, wherein the second light shielding pattern comprises an edge having a plurality of curved portions on a plane.

2 . The window member of claim 1 , wherein the second light shielding pattern has a multilayer structure.

3 . The window member of claim 1 , wherein the second light shielding pattern comprises a first layer disposed on the base substrate and a second layer disposed on the first layer, and a side surface of the first layer and a side surface of the second layer are aligned on a cross-section.

4 . The window member of claim 1 , wherein the edge comprises an outer edge and an inner edge configured to define the signal transmission area, and the inner edge is a closed line.

5 . The window member of claim 4 , wherein at least one of the outer edge and the inner edge comprises the plurality of curved portions.

6 . The window member of claim 4 , wherein a distance between the outer edge and the inner edge is about 0.05 mm to about 1.50 mm.

7 . The window member of claim 1 , wherein the signal transmission area is provided in plurality.

8 . The window member of claim 1 , wherein the base substrate is a glass substrate, and the second light shielding pattern is directly disposed on one surface of the glass substrate.

9 . The window member of claim 1 , wherein the first light shielding pattern and the second light shielding pattern have a same laminated structure.

10 . The window member of claim 1 , wherein each of the curved portions comprises a curved line recessed toward the inside of the second light shielding pattern on the plane.

11 . The window member of claim 1 , wherein a pitch of the curved portions is about 5 μm to about 30 μm.

12 . The window member of claim 1 , wherein the second light shielding pattern comprises a first layer having a black color and a second layer having a non-black color.

13 . An electronic apparatus comprising:
a display panel comprising a display area configured to display an image and a non-display area disposed adjacent to the display area; a window member disposed on the display panel; and an input sensor disposed between the display panel and the window member, wherein: the window member comprises a base substrate and a light shielding pattern disposed on a bottom surface of the base substrate while being surrounded by the display area on a plane and providing a signal transmission area at an inner side thereof; and the light shielding pattern comprises an edge having a plurality of curved portions on the plane.

14 . The electronic apparatus of claim 13 , further comprising an electronic module disposed below the window member and the display panel and aligned with the signal transmission area.

15 . The electronic apparatus of claim 14 , wherein the electronic module comprises a camera module, an infrared sensor, or a photo sensor.

16 . The electronic apparatus of claim 13 , wherein at least one of the display panel and the input sensor comprises a first area corresponding to the signal transmission area and a second area adjacent to the first area, and the first area has a light transmittance greater than the second area.
