  • Patent number: 7989807
    Abstract: Contamination is blocked from material of a color filter layer provided on a thin-film transistors (TFT) supporting substrate by sealing over the color filter layer with an inorganic insulating layer. During mass production manufacture, a plasma surface cleaning step is employed after the color filter layer is deposited but before the inorganic insulating layer is deposited. A low temperature CVD process is used to deposit the inorganic insulating layer with a substantially uniform thickness conformably over the color filter layer including conformably into openings provided through the color filter layer.

  • Patent number: 7826011
    Abstract: In a light transmitting, color image display unit, a top surface of a black matrix partition wall exhibits lyophobicity relative to in-solution pigment particles while sidewall surfaces of the black matrix exhibit lyophilicity relative to in-solution pigment particles. This allows the pigment containing solutions to abut without repulsion against the sidewall surfaces. Consequently, it is possible to prevent color filter solutions deposited through an inkjet deposition process from overflowing over the lyophobic partition wall tops into adjacent pixel regions and it is also possible to conformably define color filters of consistent thickness between the black matrix partition walls.
