Abstract: A display device includes a display panel from which light is emitted; and an optical film to which the light from the display panel is incident. The optical film includes: a first pattern layer having a first refractive index, and a second pattern layer having a second refractive index lower than the first refractive index, the second pattern layer including a plurality of hollow inorganic particles. The second pattern layer which has the second refractive index lower than the first refractive index and includes the plurality of hollow inorganic particles, is disposed further from the display panel than the first pattern layer.

Abstract: An optical film includes a first pattern layer including a first base portion and first protruding portions disposed on the first base portion to be spaced apart from each other and having a first refractive index and a second pattern layer disposed on the first pattern layer and having a second refractive index. Each of the first protruding portions includes a first sub-protruding portion having a first width in a cross-section perpendicular to the first base portion, a second sub-protruding portion disposed between the first base portion and the first sub-protruding portion and having a width that increases from the first sub-protruding portion to the first base portion, and a third sub-protruding portion disposed on the first sub-protruding portion and having a width that decreases as a distance from the first sub-protruding portion increases.

Abstract: An optical film may include a first pattern layer having a first refractive index and including a base portion and a plurality of protrusions on the base portion x, and a second pattern layer disposed on the first pattern layer and having a second refractive index different from the first refractive index. Each of the protrusions may include n sub-protrusions (n is an integer of 2 or greater), which are stacked in a thickness direction of the base portion. Each of the n sub-protrusions may have a quadrilateral shape. A side surface of the protrusion defined by the n sub-protrusions may include at least one step portion. The optical film improves display quality of a display device in front and lateral directions.

Abstract: A display device includes a base layer, a first pixel transistor, a first gate line, a first data line electrically connected to the first pixel transistor, a first pixel electrode electrically connected to the first pixel transistor and overlapping the first data line in a plan view, and a porous layer. The porous layer is disposed between the first data line and the first pixel electrode and includes a matrix including a polymer resin and a plurality of void portions defined in the matrix. The display device is capable of displaying a sharp image because the porous layer alleviates or prevents a crosstalk between the first data line and the first pixel electrode.
