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 method for manufacturing a window member, the method comprising:
providing a base substrate; and
forming a light shielding layer comprising a first light shielding pattern on one surface of the base substrate and a second light shielding pattern spaced apart from the first light shielding pattern and configured to define a signal transmission area at an inner side thereof,
wherein:
the forming of the light shielding layer comprises:
forming a preliminary light shielding pattern corresponding to the second light shielding pattern on the one surface of the base substrate; and
irradiating a laser beam to a partial area of the preliminary light shielding pattern;

the preliminary light shielding pattern defines a preliminary signal transmission area at an inner side thereof; and
in the irradiating the laser beam, the laser beam is irradiated to an outer edge area adjacent to an outer edge of the preliminary light shielding pattern and an inner edge area adjacent to an inner edge configured to define the preliminary signal transmission area.

2. The method of claim 1 , wherein the irradiating the laser beam comprises:
irradiating the inner edge area with the laser beam to form the signal transmission area; and
irradiating the outer edge area adjacent to an outer edge of the preliminary light shielding pattern with the laser beam.

3. The method of claim 1 , wherein the irradiating the laser beam comprises irradiating the laser beam from above a top surface of the base substrate.

4. The method of claim 1 , wherein the second light shielding pattern has a multilayer structure.

5. The method 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.

6. The method of claim 1 , wherein the signal transmission area is provided in plurality.

7. The method of claim 1 , wherein the signal transmission area is aligned with an electronic module disposed under the base substrate, and the electronic module comprises a camera module, an infrared sensor, or a photo sensor.
