Claim AA areas) 1, the intermediate region of effective display area domain 1 is provided with the first pixel cell A in array fashion.Frame glue 30, which is located at, to be had
The periphery of viewing area 1 is imitated, effective display area domain 1 has the transition region d at edge, and positioned at the pixel at the edge of effective display area domain 1
Penetrance be less than the penetrance of the pixel in other regions in effective display area domain 1, i.e. the penetrance of transition region d pixel is less than
First pixel cell A penetrance.
As shown in Fig. 2 because the penetrance of the transition region d at edge pixel is less than the first pixel cell A of intermediate region
Penetrance, closer to frame glue 30, the penetrance of pixel is lower so that the penetrance positioned at the pixel close to frame glue 30 is less than leaning on
Paracentral first pixel cell A, compared with prior art, the appropriate reduction of the throughput of the light of edge pixel of the invention,
Negative compensation is carried out to edge light leak, (i.e. the brightness of transition region d) is minimized, liquid for the marginal zone for the surrounding that script brightness edges up
When crystal driving voltage is identical, edge brightness and intermediate luminance are substantially at same level, so as to reduce the risk of edge light leak.
