The invention provides a display panel and a display device. The display panel comprises total reflection electrodes positioned on a substrate, luminescent devices positioned in the sides, far from the substrate, of the total reflection electrodes respectively, a semi-transmitting electrode positioned in the side, far from the substrate, of the luminescent devices, and a light taking layer positioned in the side, far from the substrate, of the semi-transmitting electrode; and the thickness of the light taking layer corresponding to an area of the first luminescent device is greater than that of the light taking layer corresponding to an area of the second luminescent device, the thickness of the light taking layer corresponding to the area of the second luminescent device is greater than that of the light taking layer corresponding to an area of the third luminescent device, the wavelength of light emitted by the first luminescent device is higher than that of light emitted by the second luminescent device, and the wavelength of light emitted by the second luminescent device is higher than that of light emitted by the third luminescent device. Thus, the color offset under a directview and an inclined view can be reduced, and a display effect of the display panel can be improved.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] In the prior art, in order to enhance the intensity of the light emitted vertically from the display panel, a microcavity structure is provided in the display panel. The microcavity structure can enhance the light of a specific wavelength in the direction perpendicular to the display panel. As the viewing angle increases, the cavity length of the microcavity structure also increases, because the longer the cavity length of the microcavity structure, the more serious the blue shift of the light under the action of the microcavity structure, so at the viewing angle When the value is larger, the blue shift of the display panel is more serious, so that the display effect of the display panel is worse at a larger viewing angle of the display panel, thereby affecting the display effect of the display panel. ...
