experiment example

[0229] The following evaluation was performed about the photosensitive composition manufactured by the Example and the comparative example of Table 1, and the result is described in following Table 2.

[0230] (1) Sensitivity determination

[0231] On a glass substrate (Corning 1737, manufactured by Corning Corporation) with a thickness of 0.7 mm, utilize a spin coater (Spinner) to coat the photosensitive resin compositions of Examples and Comparative Examples respectively, and heat on a heating plate at 100° C. for 125 seconds The solvent was evaporated to form a pre-insulation layer with a thickness of 4.0 μm.

[0232] Thereafter, in order to obtain a contact hole pattern with a diameter of 10 μm, exposure was performed by an i-line stepper (NSR-205i11D, Nikon Corporation) using a mask having a quadrangular pattern opening with an exposed portion having a side of 10 μm.

[0233] The exposed substrate was developed with 2.38% tetramethylammonium hydroxide aqueous solution as...

Abstract

The invention provides a positive photosensitive resin composition, an insulating film and an image display device. The positive photosensitive resin composition includes a binder resin, an antioxidant containing a difunctional epoxy compound, a photoacid generator, and a solvent. By means of the interaction between the binder resin and the antioxidant, an insulating film having improved transmittance and reliability can be formed.

Description

technical field [0001] The present invention relates to a positive photosensitive resin composition, an insulating film produced from the positive photosensitive resin composition, and an image display device including the insulating film. More specifically, it relates to a positive photosensitive resin composition including a photosensitive resin and a photoacid generator, an insulating film produced from the positive photosensitive resin composition, and an image display device including the insulating film. Background technique [0002] For example, photosensitive resin compositions are used to form various photocurable insulating patterns such as photoresists, insulating films, protective films, black matrices, and columnar spacers of display devices. For example, inorganic insulating films such as silicon oxides and silicon nitrides have high dielectric constants, so there is an increasing demand for low-dielectric organic insulating films. To form the organic insulatin...
