Window panel, manufacturing method thereof, and display apparatus including the window panel

A display apparatus comprising:

• a display panel;
• and
• a transparent window panel on a light exit plane of the display panel,
• wherein the transparent window panel comprises:
• an adhesion-base layer having a first surface and a second surface opposite to the first surface, the adhesion-base layer comprising a thermoplastic polymer;
• a first film on the first surface of the adhesion-base layer, the first film comprising a first plastic layer and a first surface hardness layer on the first plastic layer;
• and
• a second film on the second surface of the adhesion-base layer, the second film comprising a second plastic layer and a second surface hardness layer on the second plastic layer,
• wherein the adhesion-base layer, the first plastic layer, and the second plastic layer include a same material.

A method of manufacturing a window panel, the method comprising:

• preparing a first film comprising a first plastic layer and a first surface hardness layer on the first plastic layer;
• preparing a second film comprising a second plastic layer and a second surface hardness layer on the second plastic layer;
• disposing the first film and the second film parallel to each other;
• providing a thermoplastic polymer of a same material as the first plastic layer and the second plastic layer between the first film and the second film;
• and
• forming an adhesion-base layer by curing the thermoplastic polymer.
