Since the first optical compensating layer 240 is set to photosensitive layer 232 toward the surface of first surface 211, and it is located at sense
Between photosphere 232 and transparent conductive oxide film 220, thus etching region and non-etched area reflectivity the difference is that: etching
Area, reflection and transparent conductive oxide film of first optical compensating layer 240 with 220 interface of transparent conductive oxide film

The difference of the two reflectivity is set to be less than the range that human eye can identify, to have the function that eliminate etching line.
For example, the refractive index n1 of the first optical compensating layer 240 takes 1.75, the refractive index of transparent conductive oxide film 220
1.9 are taken, the refractive index of substrate 210 takes 1.6.The reflectivity in etching region and non-etched area the difference is that:
Referring to Fig. 4, etching region: the reflection of the first optical compensating layer 240 and 220 interface of transparent conductive oxide film

R (reflectivity of the first optical compensating layer and transparent conductive oxide film interface)=(1.9-1.75)2/(1.9
+1.75)2=0.17%；
R (reflectivity at transparent conductive oxide film and substrate interface)=(1.9-1.6)2/(1.9+1.6)2=
0.73%；
R (reflectivity at the first optical compensating layer and substrate interface)=(1.75-1.6)2/(1.75+1.6)2=

The reflection of 220 interface of oxide film and transparent conductive oxide film 220 and 250 interface of the second optical compensating layer
Reflection；Non-etched area, the reflection of 250 interface of the first optical compensating layer 240 and the second optical compensating layer.
Specific in Fig. 6 and Fig. 7 illustrated embodiment, the refractive index n2 of the second optical compensating layer 250 is between 1.55 and 1.8
Between.Therefore it is similar between the second optical compensating layer 250 and the first optical compensating layer 240, can reduce etching region with it is non-
The difference of the reflectivity of etching region further slows down etching line phenomenon.
The light transmittance of second optical compensating layer 250 is greater than 90%.For example, the light transmittance of the second optical compensating layer 250 can be with
It is 95%.The light transmittance of second optical compensating layer 250 is higher, and light transit dose is bigger, can further slow down etching line phenomenon.
But light transmittance it is bigger when, to the cost of manufacture of the second optical compensating layer 250 and require it is higher, therefore by the second optical compensating layer
250 light transmittance is set greater than in 90% zone of reasonableness.
For example, the refractive index n1 of the first optical compensating layer 240 takes 1.75, the refractive index of transparent conductive oxide film 220
1.9 are taken, the refractive index of substrate 210 takes 1.6, and the refractive index of the second optical compensating layer 250 takes 1.65.Etching region and non-etched area
Reflectivity the difference is that:
Referring to Fig. 7, etching region: the reflection of the first optical compensating layer 240 and 220 interface of transparent conductive oxide film
With the reflection of 250 interface of transparent conductive oxide film 220 and the second optical compensating layer.Non-etched area, the first optical compensation
The reflection of layer 240 and 250 interface of the second optical compensating layer.According to the relationship of reflectivity and refractive index, first can be calculated
The reflectivity of optical compensating layer 240 and 220 interface of transparent conductive oxide film, transparent conductive oxide film 220 and the
The reflectivity of two optical compensating layers, 250 interface and the first optical compensating layer 240 are anti-with 250 interface of the second optical compensating layer
Rate is penetrated, as follows respectively:
R (reflectivity of the first optical compensating layer and transparent conductive oxide film interface)=(1.9-1.75)2/(1.9
+1.75)2=0.17%；
R (reflectivity of transparent conductive oxide film and the second optical compensating layer interface)=(1.9-1.65)2/(1.9
+1.65)2=0.50%；
R (reflectivity of the first optical compensating layer and the second optical compensating layer interface)=(1.75-1.65)2/(1.75+
1.65)2=0.086%.
Therefore, reflectivity difference=0.17%+0.50%*95%-0.086%=of etching region and non-etched area
0.56%.So the first optical compensating layer 240 and the second optical compensating layer 250 substantially reduce etching region and non-etched area
Difference in reflectivity has the function of slowing down etching line, by accurately adjusting, the difference of reflectivity can be enable less than human eye institute
The range of identification, to have the function that eliminate etching line.
