Claim 10:
11. A method for manufacturing a cover glass of an electronic device, the method comprising:
preparing a glass plate;
wet spraying a first coat layer, the first coat layer at least partially including a network structure with multiple protrusion-and-depression shapes formed by inorganic polysilazane coated on a surface of the glass plate, wherein the first coat layer has a hazing exceeding 5% and a transmittance of less than 91%, on a surface of the prepared glass plate;
stream hardening the first coat layer in a temperature range of 100° C. to below 200° C. for a time range of 30 minutes to 120 minutes;
processing the stream hardened first coat layer with peroxide in a temperature range at 30° C. to 200° C. for three hours; and
depositing a second coat layer on a surface of the first coat layer, the second coat layer including a shape corresponding to the network structure of the first coat layer;
wherein the first coat layer includes silicon (Si), oxygen (O), and at least one impurity,
wherein Si—O bonds are at least 80% by-weight of mass of the first coat layer, and
wherein the hazing denotes a state in a middle of changing from transparent to opaque depending on a percent of the hazing,
wherein the multiple protrusion-and-depression shapes includes a plurality of valley portions and peak portions,
wherein the plurality of valley portions has a thickness ranging from 300 nm to 600 nm, and the peak portions have a thickness ranging from 0.6 μm to 2 μm, and
wherein a thickness of the first coat layer is implemented in a range of a thickness of the plurality of valley portions and a thickness of the peak portions so that a degree of the hazing is not lowered.
