Polaroid includes: base and the polarizing layer for being attached at base.As shown in figure 12, polarizing layer includes first area
121 and second area 122, and the light transmission of second area 122 is better than the light transmission of first area 121.Optionally, polarisation
Layer further includes third region.Introduction explanation in relation to polaroid can be found in foregoing embodiments, and details are not described herein again.
Optionally, as shown in figure 13, a kind of schematic diagram of display panel 20 is illustrated.Display panel 20 wraps
It includes: substrate 21 and the display layer 22 on substrate 21.
Display layer 22 is for realizing the function of showing image.Optionally, display layer 22 includes main viewing area 221 and auxiliary display
Area 222.Main viewing area 221 and auxiliary viewing area 222 are provided with display function.The quantity of auxiliary viewing area 222 can be one, can also
To be multiple.In Figure 13, it is 1 with the quantity of auxiliary viewing area 222 and is schematically illustrated.Display layer 22 includes main viewing area
221 and the two distinct types of display area in auxiliary viewing area 222, but main viewing area 221 and auxiliary viewing area 222 are physically
Be a unified entirety namely display layer 22 it is integral structure, is not divided into multiple independent compositions mutually
Part.
If display layer 22 includes multiple independent component parts mutually, and these component parts are spliced to form display layer
22, then certain interval is certainly existed at stitching position, eventually leads between the display content of each component part that there are gap, nothings
Method reaches display content one integrated mass, the gapless display effect of entire display layer 22.But in the embodiments of the present disclosure,
Since main viewing area 221 and auxiliary viewing area 222 are being physically a unified entirety, between the two and between being not present

To display content one integrated mass, the gapless display effect of entire display layer 22.
In addition, substrate 21 is integrated, that is, main viewing area 221 and auxiliary viewing area 222 are formed in one piece of substrate
On.If the corresponding first substrate region in main viewing area 221 and the corresponding the second substrate region in auxiliary viewing area 222 use identical material
Material is made, then one piece of whole plate that substrate 21 is made of the same material；If the corresponding first substrate region in main viewing area 221
It is made with the corresponding the second substrate region in auxiliary viewing area 222 of different materials, then related process can be used first substrate
Region and the splicing of the second substrate region, and make stitching portion seamless, form the substrate 21 of integral structure.
Optionally, the light transmission of auxiliary viewing area 222 is better than the light transmission of main viewing area 221.For example, auxiliary viewing area
222 light transmittance is greater than the light transmittance of main viewing area 221.By relevant manufacturing process, the saturating of auxiliary viewing area 222 can be made
Optical property gets a promotion.For example, by lighting control device (such as driving circuit, TFT (Thin of the sub-pixel in auxiliary viewing area 222
Film Transistor, thin film transistor (TFT)), the components such as holding capacitor) be set to outside auxiliary viewing area 222 so that auxiliary display
The light transmittance in area 222 can be improved.In another example at least one sub-pixel sequence is formed in auxiliary viewing area 222, at least one son
Include at least two sub-pixels in each sub-pixel sequence in pixel sequence, and includes in any one sub-pixel sequence
The color of each sub-pixel is identical, in this way, allowing the sub-pixel of same color to share same cabling, in auxiliary viewing area 222
Cabling quantity can reduce, optimization cabling layout so that the light emission controllers such as holding capacitor, TFT in auxiliary viewing area 222
The quantity of part is reduced, to improve the light transmittance of auxiliary viewing area 222.For another example by the ruler of the sub-pixel in auxiliary viewing area 222
It is very little, it is set greater than the size of the sub-pixel in main viewing area 221, so that the pixel distribution density in auxiliary viewing area 222
Less than the pixel distribution density in main viewing area 221, in this way, can be reduced as far as in auxiliary viewing area 222
Cabling quantity, optimization cabling layout, and make PDL (Pixel Delineation Layer, the pixel between pixel and pixel
Definition layer) become the shape of as far as possible regular bulk, so that transmission region (including sub-pixel and PDL institute in auxiliary viewing area 222
Occupied area domain) better light transmission can be obtained.
Optionally, main viewing area 221 is corresponding with first area 121, and auxiliary viewing area 222 is corresponding with second area 122.
That is, main viewing area 221 has same or similar size and shape with first area 121, main viewing area 221 is along perpendicular to aobvious
The view field in display screen direction is overlapped with first area 121 along the view field perpendicular to display screen direction.Auxiliary viewing area 222 with
Second area 122 has same or similar size and shape, and auxiliary viewing area 222 is along the view field perpendicular to display screen direction
It is overlapped with second area 122 along the view field perpendicular to display screen direction.
Optionally, in the case where polarizing layer further includes third region, display layer can also include transition viewing area, the mistake
Viewing area is crossed between main viewing area and auxiliary viewing area, and transition viewing area is corresponding with third region.That is, transition is shown
Area and third region have same or similar size and shape, and transition viewing area is along the view field perpendicular to display screen direction
It is overlapped with third region along the view field perpendicular to display screen direction.Transition viewing area has with main viewing area and auxiliary viewing area
Different pixel distribution forms.For example, the size of the sub-pixel in transition viewing area, greater than the ruler of the sub-pixel in main viewing area
It is very little, and the size for the sub-pixel being less than in auxiliary viewing area.The size of each sub-pixel in transition viewing area, can be identical,
It can be different.For example, the size closer to the sub-pixel of auxiliary viewing area is bigger, the size closer to the sub-pixel of main viewing area is got over
It is small.By the above-mentioned means, the resolution ratio transition between main viewing area and auxiliary viewing area can be made more smooth naturally, being promoted whole
