Abstract
A display panel includes a first base layer, a second base layer facing the first base layer, and in order between the first base layer and the second base layer, from the first base layer: an image display layer which provides light, a polarization layer which receives the light from the image display layer and transmits a polarized component of the light toward the second base layer, and a lens layer.
Claims17
A display panel, comprising:
- a first base layer;
- a second base layer facing the first base layer;
- an image display layer which is between the first base layer and the second base layer and provides light;
- a polarization layer which is between the image display layer and the second base layer, receives the light from the image display layer and transmits a polarized component of the light toward the second base layer, the polarization layer including a plurality of patterns extending along an extension direction and spaced apart from each other along a direction intersecting the extension direction;
- and
- a plurality of pattern layers which are between the polarization layer and the second base layer and have refractive indices different from each other,
- wherein the plurality of pattern layers which are between the polarization layer and the second base layer includes:
- a lower refractive layer and an upper refractive layer which face each other, the lower refractive layer having a refractive index greater than a refractive index of the upper refractive layer, and
- the lower refractive layer which has the refractive index greater than the refractive index of the upper refractive layer defining a plurality of protrusions of a lens layer which extend along the direction in which the plurality of patterns of the polarization layer are spaced apart from each other.
