The invention discloses a display panel of a horizontal electric field type, a manufacturing method of the display panel, and a display device. A first compensation film layer is arranged between an opposite substrate and an array substrate, the sum of the phase difference of the first compensation film layer and the phase difference of a liquid crystal layer is integer multiple times of the wavelength of incident light, and the optical axis direction of the first compensation film layer is parallel to the initial optical axis direction of liquid crystal molecules in the liquid crystal layer.When optical anisotropy is generated by the opposite substrate and the array substrate under the condition of bearing uneven external force and the polarization state of permeating light is changed, the first compensation film layer can compensate for the phase delay of the polarization light passing through the liquid crystal layer, after light passes through the opposite substrate, the array substrate, the liquid crystal layer and the first compensation film layer, the total phase delay is nearly or equally integer multiple times of the wavelength of incident light, and light restores the original polarization state to a certain extent. In this way, in the dark state, most of light cannot emit out of the display panel, and the dark-state light leakage problem is solved.

The invention discloses a display panel with a horizontal electric field, a making method thereof and a display device. A first compensation film is arranged between an opposite substrate and an arraysubstrate, a difference between phase difference of the first compensation film and that of a liquid crystal layer is integral multiples of incident light wavelength, and optical axis direction is perpendicular to initial optical axis direction of liquid crystal molecules in the liquid crystal layer. When polarization state of penetrating light is changed due to optical anisotropy generated whenthe opposite substrate and the array substrate receive nonuniform external force, the first compensation layer can offset phase delay when polarized light goes through the liquid crystal layer to enable total phase delay to be close to or equal to integral multiple of the incident light wavelength after light goes through the opposite substrate, the array substrate, the liquid crystal layer and the first compensation film, so that the light is enabled to be restored to original polarization state to a certain degree. In this way, when in a dark state, most of the light cannot be emitted from adisplay panel, so that the problem of dark-state light leakage is improved.
