  • Publication number: 20240126169
    Abstract: Provided is a photosensitive resin composition including a reactive unsaturated compound, an alkali soluble resin, an initiator, and a pigment. The reactive unsaturated compound is selected to cause the composition to exhibit high-resolution pattern properties that facilitate forming a pixel defining film in a display device. The reactive unsaturated compound may be an acryl-based compound having at least three ethylenically unsaturated double bond groups in molecules and having a viscosity of about 200 mPa s to about 280 mPa s at 40° C. A display device including such pixel defining film is also presented.

  • Patent number: 8092982
    Abstract: Photosensitive paste compositions, barrier ribs of plasma display panels (PDPs) prepared using the same, and PDPs including the barrier ribs are provided. The photosensitive paste composition includes an organic-inorganic complex sol and an inorganic material, wherein the average refractive index (N1) of the organic-inorganic complex sol and the average refractive index (N2) of the inorganic material satisfy the equation ?0.2?N1?N2?0.2. Using the photosensitive paste composition, patterned barrier ribs for PDPs having high resolution and high precision can be made by exposure to light only once. Barrier ribs having higher reflective indices than conventional barrier ribs can also be obtained.

  • Publication number: 20080227033
    Abstract: Photosensitive paste compositions, plasma display panels (PDP) manufactured using the same, and methods of manufacturing the PDPs are provided. In one embodiment, a photosensitive paste composition includes an inorganic component and an organic component, where the organic component includes a cross-linking agent including a monoacrylate, where the monoacrylate is present in an amount ranging from about 50 to about 100 weight % with respect to a total weight of the cross-linking agent. In another embodiment, a PDP is manufactured using the photosensitive paste composition. In yet another embodiment, a method of manufacturing the PDP is provided. The inventive photosensitive paste compositions can fundamentally prevent film twisting, disconnection or detachment by minimizing stress on the patterned film during sintering, thereby minimizing modifications due to shrinkage.

  • Publication number: 20080026320
    Abstract: A photosensitive paste composition includes a metal oxide sol and an inorganic material, wherein the average light refractive index (N1) of the metal oxide sol and the average light refractive index (N2) of the inorganic material satisfy Equation 1 below. a barrier rib of a PDP prepared using the same and a PDP including the barrier rib: ?0.2?N1?N2?0.2.Equation 1 A barrier rib of a plasma display panel is prepared using the photosensitive past composition. Since a pattern of a barrier rib for a PDP having high resolution and high precision can be made by only a single exposure to light, and a barrier rib having a higher reflective index than a conventional barrier rib can also be provided, a PDP including the barrier rib can have a high luminance.
