Interior uniform thickness is finally exposed etching to the second insulating sublayer layer 112 in the first viewing area AA1, forms the first display
The difference in thickness of area AA1 and the second viewing area AA2.
The above are the embodiments of display panel provided by the invention, and the present invention also provides a kind of display device, the displays
Device includes any one display panel provided by the invention, has its technical characteristic and corresponding technical effect, herein no longer
It repeats.
Figure 15 is the schematic diagram for the display device that an embodiment of the present invention provides, as shown in figure 15, the display device packet
Shell 01 and the display panel 02 in shell 01 are included, which is the display panel with relief area, the application
Display device can also include other display panels, it is specific to repeat no more as described above, at this.
Through the foregoing embodiment it is found that display panel provided by the invention and display device, at least realizing following has
Beneficial effect:
Different data lines is loaded for pixel present on display panel, it is right by the way that the capacitive load of differentiation is arranged
The difference of pixel load compensates, so that the difference of overall load reduces on each data line, it is whole to be conducive to raising display panel
The harmony that body is shown, meanwhile, when the capacitive load of differentiation is arranged, by adjusting the thickness of the insulating layer between capacitor the two poles of the earth
Degree, that is, adjustment data line with the first signal wire crossover position at a distance from realization capacitor differentiation, to the battle array of display panel
Wiring in column substrate is without influence, for high-resolution display panel, in the insufficient situation of wiring space,
The harmony that display panel is integrally shown can be realized while guaranteeing high-resolution.
Although some specific embodiments of the invention are described in detail by example, the skill of this field
Art personnel it should be understood that example above merely to being illustrated, the range being not intended to be limiting of the invention.The skill of this field
