The invention provides a display panel and a displaying device. The display panel comprises multiple pixel groups, each pixel group comprises a first pixel unit and a second pixel unit, wherein a control end of the first switch is coupled with a first scanning wire, a first end is coupled with a first data wire, a second end is coupled with a first sub pixel, a control end of the second switch iscoupled with the first scanning wire, a first end is coupled with the first data wire, a second end is coupled with a first primary pixel, the second pixel unit comprises a third switch and a fourth switch, a control end of the third switch is coupled with a second scanning wire, a first end is coupled with the first data wire, a second end is coupled with a second sub pixel, a control end of thefourth switch is coupled with the second scanning wire, a first end is coupled with the first data wire, and a second end is coupled with a second primary pixel. The first and second switches are located in the same column, and the third and fourth switches are located in the same column. The first and third switches are located in a sub pixel region, the second and fourth switches are located ina primary pixel region, and the area of the sub pixel region is greater than that of the primary pixel region.

The invention relates to an optical composite film and a display panel. An optical composite film includes a reflective grating film layer, a single optical axis optical film layer and a base layer, the single optical axis optical film layer includes a plate-shaped part and a plurality of refraction parts, the plate-shaped part is laminated on the reflective grating film layer, and a plurality of The refraction part is formed on the side of the plate-shaped part away from the reflective grating film layer, and the multiple refraction parts are arcuate columns or square prisms; the base layer is stacked on the side of the plate-shaped part close to the refraction part, and the multiple refraction parts are accommodated in In the base layer, the refractive index of the base layer is smaller than the extraordinary light refractive index of the single-axis optical film layer. The above-mentioned optical composite film can not only improve the large viewing angle deflection of the display panel, but also make the thickness of the display panel thinner.

The present application relates to an optical film layer and a display device. The optical film layer comprises: a first single optical axis optical layer, a plurality of grooves being formed on one side of the first single optical axis optical layer; a second single optical axis optical layer comprising a plate-shaped part and a plurality of protrusion structures matching the grooves in shape and size attached on one side of the plate-shaped part, the extraordinary refractive index of the second single optical axis optical layer being greater than the ordinary refractive index of the first single optical axis optical layer; and a first grating layer laminated on one side of the second single optical axis optical layer away from the first single optical axis optical layer or embedded on one side of the second single optical axis optical layer away from the first single optical axis optical layer.
