Liquid crystal on silicon (lcos) device and lcos display panel

A liquid crystal on silicon (LCOS) device, comprising:

• a substrate;
• at least two first pixel electrodes each having a substantially rectangular cross-section defining a first diagonal direction, a second diagonal direction and a length direction, each of the at least two first pixel electrodes having four cutaway corners, the at least two first pixel electrodes being arranged on the substrate along the first diagonal direction;
• a first insulating layer, which is filled between sidewalls of adjacent first pixel electrodes and covers the first pixel electrodes;
• at least two second pixel electrodes each having a substantially rectangular cross-section and arranged on the first insulating layer along the second diagonal direction, wherein in a projection plane parallel to a surface of the substrate:
• the second pixel electrodes are alternately arranged with the first pixel electrodes in the length direction;
• and an inter-pixel gap is formed between corners of adjacent second pixel electrodes along the second diagonal direction and also between cutaway corners of adjacent first pixel electrodes along the first diagonal direction;
• and
• a second insulating layer, which is filled between sidewalls of adjacent second pixel electrodes,
• wherein a gap is formed between adjacent cutaway corners of adjacent first pixel electrodes, an edge portion along each side of each of the second pixel electrodes overlapping an underlying side of a corresponding one of the first pixel electrodes, the inter-pixel gap being smaller in area than the gap.
