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.
Claims21
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 on the rear surface of the panel layer, the first support layer including a first material;
- a light refracting layer on a rear surface of the first support layer, the light refracting layer including a second material;
- a second support layer on a rear surface of the light refracting layer, the second support layer including the first material;
- and
- a side cover on the inclined portion of the complex sheet, the side cover covering an opening at a side surface of the light refracting layer.

A complex sheet, comprising:
- a first support layer including a first material;
- a light refracting layer on the first support layer, the light refracting layer including a plurality of light refracting elements of a second material that is different from the first material;
- a second support layer on the light refracting layer, the second support layer including the first material;
- and
- a side cover disposed at an angle on the first support layer, the light refracting layer, and the second support layer, the side cover covering an opening at a side surface of the light refracting layer due to a shape of the plurality of light refracting elements.
