Abstract

A display panel comprises a first substrate, a second substrate and a pixel array. The pixel array is disposed between the first substrate and the second substrate and comprises a pixel electrode and a data line. The data line is disposed adjacent to the pixel electrode and disposed above a side of the first substrate facing the second substrate. The pixel electrode comprises a first trunk electrode and a plurality of branch electrodes. An extension of the first trunk electrode along a first direction crosses the data line and the first trunk electrode connects to the branch electrodes. The branch electrodes extend along a second direction. An angle y is formed by the first direction and the second direction, x is the value of the ppi of the display panel, and x and y satisfy the following equations:

A 1=−1.28×10 −5 ( x ) 3 +0.0047722( x ) 2 −0.383068( x )+59.494865,

B 1=−2.38×10 −5 ( x ) 3 +0.0093751( x ) 2 −1.098394( x )+81.919357,

B1<y<A1,

45°<y≦70°.
