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:A1=−1.28×10−5(x)3+0.0047722(x)2−0.383068(x)+59.494865,B1=−2.38×10−5(x)3+0.0093751(x)2−1.098394(x)+81.919357,B1<y<A1,45°<y≦70°.
