Definitions
- the present invention relates to a photosensitive composition comprising an organometallic compound and a polysiloxane copolymer, and a method for preparing the same, and more particularly, to a photosensitive composition comprising a copolymer of an organometallic compound and polysiloxane that can be used in a photosensitive material for a display or semiconductor and to a manufacturing method thereof.
- optical elements such as a display, a light emitting diode, a solar cell, WHEREIN:
- Various proposals for the improvement of the new light utilization efficiency and energy saving are made
- a liquid crystal display there is known a method of increasing the aperture ratio of a display device by coating and forming a transparent flattening film on a TFT element and forming a pixel electrode on the flattening film.
- Structure diagram of an organic EL device From a method in which a light emitting layer is deposited on a transparent pixel electrode formed on a substrate and light is emitted from the substrate side (bottom emission), a transparent pixel electrode on a planarization film coated on a TFT element and the above
- the method of improving the aperture ratio similarly to a liquid crystal display is proposed by making light emission from the light emitting layer of a TFT element into a system (top emission) which is taken out on the opposite side.
- a material for such a flattening film for TFT substrates a material obtained by combining an acrylic resin and a quinonediazide compound is known.
- these materials do not rapidly deteriorate material properties at high temperatures of 200° C. or higher, but at 230° C. or higher, decomposition begins gradually, and the transparent film is colored due to a decrease in film thickness or high-temperature treatment of the substrate, resulting in a decrease in transmittance.
- it cannot be used in a process of forming a film on the transparent film material at a high temperature using an apparatus such as PE-CVD.
- acrylic materials cannot be said to be optimal materials for use in high-temperature processes or devices affected by impurities.
- an acrylic material to which heat resistance is imparted generally has a high dielectric constant. For this reason, power consumption increases due to an increase in parasitic capacitance due to the insulating film, or the quality of image quality is deteriorated due to a delay of a driving signal of a liquid crystal element.
- the capacitance can be reduced by, for example, increasing the film thickness, but it is common to form a uniform coating film with a film thickness of, for example, 5 microns or more on a large glass substrate by a slit coating method or the like. It is difficult to do this, and since the amount of material used also increases, it is not preferable to increase the film thickness.
- Polysiloxane is known as a material with high heat resistance and high transparency.
- Polysiloxane is a polymer composed of trifunctional siloxane structural unit RSi (O1.5). Chemically, it is an intermediate between inorganic silica (SiO2) and organic silicon (R2SiO), but it is soluble in organic solvents and the cured product is soluble in inorganic silica. It is a specific compound exhibiting characteristic high heat resistance.
- the polymer having a siloxane skeleton generally has a low dielectric constant compared with an organic polymer, and is expected as a material for a low dielectric transparent insulating film.
- an organic layer such as a light emitting layer is used with an inkjet head.
- IJ inkjet
- the inkjet (IJ) method is a printing method that does not use a substrate, the cost for manufacturing the substrate can be reduced, and since the material is used only in the required amount for the necessary part, the material cost can also be reduced.
- dots of a desired pattern are formed by injecting an ink containing an organic layer material into a partition surrounded by a partition (hereinafter, also referred to as an "opening"), and drying and/or heating it.
- the upper surface of the barrier rib formed along the outline of the dot needs to have ink repellency to prevent the mixing of ink between adjacent dots and to uniformly apply the ink in the dot formation.
- the partition wall corresponding to the pattern of a dot is formed by the photolithographic method using the photosensitive resin composition containing the ink repellent agent.
- polysiloxane has excellent heat resistance, transparency, and chemical stability, and is applied to printed circuit board materials, window cover film materials, photosensitive materials, and the like.
- polysiloxane as a photosensitive material exhibits excellent physical properties such as flexibility, transparency, photosensitivity, and durability.
- the coating solution containing polysiloxane shows a high taper angle and a steep inclination angle with respect to the substrate surface when forming a pattern, a low taper angle and a gentle round inclination angle required for the pixel define layer of OLED materials, etc. is difficult to implement.
- there is a limitation in applying it to a process that requires a step according to height when forming a pattern such as a black column spacer.
