• Subjects: DEVICES OR ARRANGEMENTS, THE OPTICAL OPERATION OF WHICH ISMODIFIED BY CHANGING THE OPTICAL PROPERTIES OF THE MEDIUM OF THEDEVICES OR ARRANGEMENTS FOR THE CONTROL OF THE INTENSITY,COLOUR, PHASE, POLARISATION OR DIRECTION OF LIGHT, e.g.SWITCHING, GATING, MODULATING OR DEMODULATING; FREQUENCY-CHANGING; NON-LINEAR OPTICS; OPTICAL ANALOGUE/DIGITAL CONVERTERS; OPTICAL LOGIC ELEMENTS; OPTICS; PHYSICS; TECHNIQUES OR PROCEDURES FOR THE OPERATION THEREOF

A display panel and a display device are disclosed. The display panel comprises a lower substrate (1), an upper substrate (2) and a liquid crystal layer (3) disposed between the upper substrate (2) and the lower substrate (1), a lower polarizer (4) is disposed at a light incident side of the lower substrate (1), an upper polarizer (5) is disposed at a light exiting side of the upper substrate (2). The display panel further comprises a compensation layer (6) disposed between the upper substrate (2) and the liquid crystal layer (3) and configured to compensate for a residual birefringence of the substrates (1, 2) so that, in the dark display state, the polarization direction of light exiting the upper substrate (2) remains the same as the polarization direction of light before incident on the lower substrate (1).
