Claim of US Patent No. 9,832,890

1. A cover window, comprising:
a light-transmitting substrate, the light transmitting substrate including a light-transmitting region and a peripheral region
around a perimeter of the light-transmitting region;

a layer pattern with metallic appearance on the light-transmitting substrate, the layer pattern with metallic appearance being
on the peripheral region of the light-transmitting substrate and including metal or metallic compounds, the layer pattern
with metallic appearance having major top and bottom surfaces parallel to the light-transmitting substrate, and a side surface
connecting the major top and bottom surfaces of the layer pattern with metallic appearance;

a first light-blocking layer pattern on the layer pattern with metallic appearance, the first light-blocking layer pattern
having major top and bottom surfaces parallel to the light-transmitting substrate, and a side surface connecting the major
top and bottom surfaces of the first light-blocking layer pattern;

a second light-blocking layer pattern on the first light-blocking layer pattern, the second light-blocking layer pattern including:
a first portion extending on a surface of the first light-blocking layer pattern facing away from the layer pattern with metallic
appearance, and

a second portion continuous with the first portion and extending toward the light-transmitting substrate, the second portion
extending on the side surfaces of the first light-blocking layer pattern and of the layer pattern with metallic appearance,
such that the second portion is between the light-transmitting region and the peripheral region; and

a groove either in the layer pattern with metallic appearance, the groove being between the side surface of the layer pattern
with metallic appearance and the second portion of the second light-blocking layer pattern, or a groove in the first light-blocking
layer pattern, the groove being between the side surface of the first light-blocking layer pattern and the second portion
of the second light-blocking layer pattern;

wherein the major top surface of the layer pattern with metallic appearance, the major bottom surface of the layer pattern
with metallic appearance, the major top surface of the first light-blocking layer pattern, and the major bottom surface of
the first light-blocking layer pattern are coextensive with one another in the direction parallel to the light-transmitting
substrate.
