Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to just
Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.
Just there are big visual angle color offset phenomenon, inventor sends out existing display panel after study as mentioned in the background art
Existing, the reason of this phenomenon occur is that brightness decay speed is different when the light of different colours increases with visual angle.Existing view
The partially more serious display panel of role includes the display panel watched with certain viewing angles, such as vehicle-carrying display screen, due to such aobvious
Display screen viewing starting visual angle it is larger, when user perspective has it is offset when will appear biggish colour cast.
Based on above-mentioned technical problem, following solution is present embodiments provided:
Present embodiments provide a kind of display panel, comprising:
Viewing area, the viewing area include array substrate, are cascadingly set on the first of the surface of the array substrate
Electrode, light emitting functional layer and second electrode；

Zero and less than 90 degree.
Wherein, first area can be entire viewing area, or in viewing area the more serious specific region of colour cast,
Such as bent area.When first area is the more serious specific region of colour cast, display panel may include one or more the
One region, the corresponding first default angle in multiple first areas can be the same or different.Certain viewing angles, that is, user sight
With array substrate far from the angle between the surface vertical line of first electrode.
Specifically, first area can be entire display when display panel is the display panel watched under certain viewing angles
Area.For the display panel watched under certain viewing angles, since the starting visual angle of viewing is larger, when user perspective has it is offset when
Will appear biggish colour cast, by by the first electrode of viewing area adjacent to the surface of light emitting functional layer and array substrate far from first
The surface of electrode is set as having the first setting angle, and when user is when certain viewing angles watch display panel, display panel goes out
Angular and user's viewing angle of display panel are consistent or close, are equivalent to for aobvious with 0 visual angle or the viewing of lesser visual angle
Show panel, when user's viewing visual angle has certain offset relative to certain viewing angles, being equivalent to has centainly relative to 0 visual angle
Offset, guarantee user with lesser visual angle watch display panel, improve the colour cast of display panel, improve display panel and exist
Display effect under certain viewing angles.
In addition, it is bent area that first area, which can be set, since bent area is opposite for the display panel with bent area
There is certain angular deviation in the light direction of plane area, when watching display panel with biggish visual angle, bent area and flat
There are coloration differences in face area.By the way that the first electrode of bent area is arranged adjacent to the surface of light emitting functional layer and array substrate far from the
The surface of one electrode has the first setting angle, and the light direction of bent area can be made consistent or close with plane area, thus
The coloration difference for improving bent area and plane area, improves the colour cast of display panel.
It is illustrated below with reference to scheme of the specific attached drawing to the present embodiment:
