Liquid crystal display

A liquid crystal display comprising:

• a first substrate having a major horizontal imaginary reference line (X) and a major vertical imaginary reference line (Y),
• a gate line disposed on the first substrate and extending substantially parallel to the horizontal imaginary reference line (X), and
• a plurality of pixel unit cells disposed on the first substrate and each including a first field generating electrode and a second field generating electrode with an insulating layer interposed therebetween,
• wherein a first one of the first and second field generating electrodes has a plurality of cutouts defined therein,
• wherein the plurality of cutouts includes two main branch portions (MS) forming a first angle with the major vertical imaginary reference line (Y), a central section portion (CS) forming a second angle that is larger than the first angle with the vertical imaginary reference line, and two end section portion (ES) forming a third angle that is larger than the first angle with the vertical imaginary reference line, and
• wherein a value obtained by multiplying a sum of a ratio of a vertical length of the central section portion (CS) to a vertical length of the cutout and a ratio of a vertical length of the two end section portion (ES) to the vertical length of the cutout by a vertical length of the pixel unit is about 20 μm or less, wherein the vertical length is measured in the major vertical imaginary reference line (Y).
