Display panel and display device

A display device, comprising:

• a display panel including a first substrate, a second substrate disposed opposite the first substrate and an electrode layer, wherein the electrode layer is disposed on the first substrate and faces the second substrate, and includes a first trunk electrode extended along a first direction and a plurality of first branch electrodes and a plurality of second branch electrodes disposed on two sides of the first trunk electrode, the first branch electrodes or the second branch electrodes are separated by a distance (T), one of the first branch electrodes has a first curved side which is adjacent to the first trunk electrode, one of the second branch electrodes has a second curved side which is adjacent to the first trunk electrode, the first curved side and the second curved side have a first shortest distance (A) therebetween along a second direction that is perpendicular to the first direction, the first curved side has a first vertex, the second curved side has a second vertex, the first vertex is the highest point or lowest point of the first curved side along the first direction, the second vertex is the highest point or lowest point of the second curved side along the first direction, the first vertex and the second vertex have a second shortest distance (B) therebetween along the second direction, and A, B, T satisfy the equation of 0.5T≦(B−A)≦T, the unit of A, B, T is micrometer;
• and
• a backlight module disposed opposite the display panel.
