Abstract
A complex sheet, a method for producing the complex sheet, and a display panel including the complex sheet is disclosed. The complex sheet reduces moisture penetration by forming a side cover that covers an opening included in an edge of a light refracting layer that is included in the complex sheet.
Claims20
A display panel, comprising:
- a panel layer;
- a complex sheet on a rear surface of the panel layer, the complex sheet including a planar portion and an inclined portion;
- and
- a case in which the panel layer and the complex sheet are disposed,
- wherein the complex sheet includes:
- a first support layer including a first material;
- a first light refracting layer on the first support layer, the first light refracting layer including a second material;
- a second support layer on the first light refracting layer, the second support layer including a third material formed of a same material as the first material;
- and
- a side cover on the inclined portion of the complex sheet,
- wherein the side cover includes a first extension material that extends from the first material, and a second extension material that extends from the third material, and
- wherein the second extension material covers side surfaces of the first light refracting layer and the second support layer.
