Lower abbreviation OLED) layer 13, it is formed on TFT layer 12.
TFT layer 12 may include several TFT, such as play the TFT of switch and driving effect.As an example, TFT is (in figure
It is not shown) it include the semiconductor layer being cascading, gate insulating layer, grid, interlayer insulating film, source/drain and planarization
Layer.
Oled layer 13 may include multiple pixels, be separated between adjacent pixel by pixel confining layer 131.Pixel include according to
The secondary anode being stacked, organic luminous layer and cathode.Anode is electrically connected to drain electrode by the contact hole on planarization layer, so that

The macromolecule resin of heat resistance, colorant can use dyestuff or pigment.
As will be explained in later, display device can be applied to according to the display panel of the application, such as applied to
Such as the mobile terminal of mobile phone etc..Display device includes the photosensitive member as shown in Figure 7 immediately below the first transmission region 11
The 3 place side of transparent substrates of display panel 100 is arranged in part 200, photosensitive element 200.Photosensitive element 200 can be preposition camera shooting
Head and/or other photosensitive elements such as range sensor.
In the art, polaroid is generallyd use to reduce the reflectivity for the environment light for being incident on filtered region.Below will
By taking photosensitive element 200 is camera and its optical receiving end is circle as an example, it is described in detail to using the case where polaroid.
The cutting accuracy and Anawgy accuracy of polaroid are lower, and cutting error and fitting error are generally greater than 0.1mm.Cause
This is missed in the case where the size of the optical receiving end of camera is determining, for example diameter is 4mm in order to mitigate the cutting of polaroid
Difference and fitting error influence, need to make on polaroid wait be located at optical receiving end immediately below aperture (the second transmission region 22)
Diameter be greater than 4.1mm, to ensure that optical receiving end can not be blocked by polaroid and is fully exposed, and then ensure light-receiving
End can obtain enough light-inletting quantities, to guarantee pickup quality.
Further, as described above, polaroid for reducing the environment light for being incident on filtered region reflectivity, therefore need
Polaroid is set to be completely covered by the display area for the functional layer 1 being disposed below, to avoid being located at the first transmission region 11 weeks
The metal routing enclosed is reflective.In view of the cutting error and fitting error of polaroid, need to make the diameter of the aperture of polaroid small
