For, the difference of the elastic recovery rate of the elastic recovery rate of third support portion C3 and the first support portion C1 can be more than or equal to 3%, and
The difference of the elastic recovery rate of the elastic recovery rate of first support portion C1 and the second support portion C2 can be more than or equal to 3%, but not
As limit.Accordingly, though the invention shows the first support portion C1 of panel 10, the second support portion C2 and third support portion C3 to have
Substantially identical overall thickness, but have different elastic recovery rates, therefore can by the R1 of viewing area different zones match
The first support portion C1, the second support portion C2 and third support portion C3 are set, is held with adjusting the pressure in each region of liquid crystal display panel 10
By degree and panel elastic recovery rate.Significantly, since the first support portion C1, the second support portion C2 and third support portion C3
