Electronic device comprising a patterned electrode having at least one sub-portion with a first included angle between one of a plurality of branch portions and a first absorption axis

An electronic device, comprising:

• a backlight source;
• and
• a panel disposed on the backlight source, the panel comprising:
• a first substrate adjacent to the backlight source;
• a second substrate opposite to the first substrate;
• a liquid-crystal layer disposed between the first substrate and the second substrate, the liquid-crystal layer comprising a right-handed chiral dopant;
• a first polarizing plate having a first absorption axis;
• a second polarizing plate having a second absorption axis, wherein the first absorption axis is perpendicular to the second absorption axis;
• and
• a patterned electrode disposed between the first substrate and the liquid-crystal layer or between the second substrate and the liquid-crystal layer,
• wherein the patterned electrode has at least one sub-portion, the at least one sub-portion comprises a plurality of branch portions, there is a first included angle between one of the plurality of branch portions and the first absorption axis, and there is a second included angle between one of the plurality of branch portions and the second absorption axis,
• and while the patterned electrode is disposed between the first substrate and the liquid-crystal layer, the first included angle is smaller than the second included angle, and while the patterned electrode is disposed between the second substrate and the liquid-crystal layer, the first included angle is greater than the second included angle,
• wherein the patterned electrode has a plurality of sub-portions, at least some of the plurality of sub-portions comprise a first peripheral portion or a second peripheral portion, the first peripheral portion and the second peripheral portion are connected to the plurality of branch portions,
• wherein the first peripheral portion corresponds to an even-numbered edge and not an odd-numbered edge in the patterned electrode, a width of the first peripheral portion is in a range from 1 micrometer to 7 micrometers, and wherein the second peripheral portion corresponds to an odd-numbered edge and not an even-numbered edge in the patterned electrode, a width of the second peripheral portion is in a range from 1 micrometer to 7 micrometers.
