Problems solved by technology

When the exposure light passes through the phosphor layer and the color filter layer to reach the photosensitive adhesive layer, the exposure light is weakened, so it is difficult to form a fine pattern

example 1

[0057] Inventive Example 1: By mixing 3 parts by weight (3% by weight) of an azide PVA resin used as a photosensitive resin, and 25 parts by weight (25% by weight) of a water-soluble polyamide resin used as a binder resin, by weight 7 parts (7% by weight) of a water-soluble polyol was used as a water-soluble resin, and 65 parts by weight (65% by weight) of an inorganic coloring pigment were used to manufacture the adhesive layer according to Inventive Example 1. When using the adhesive layer, a satisfactory pattern can be formed through thermal transfer, exposure and water development.

example 2

[0058] Inventive Example 2: By mixing 10 parts by weight (10% by weight) of an azide PVA resin used as a photosensitive resin, and 20 parts by weight (20% by weight) of a water-soluble polyamide resin used as a binder resin, by weight 5 parts (5% by weight) of a water-soluble polyol was used as a water-soluble resin, and 65 parts by weight (65% by weight) of an inorganic coloring pigment were used to manufacture the adhesive layer according to Inventive Example 2. Although the adhesive layer requires greater exposure energy than Inventive Example 1 (Inventive Example 1 requires 20mJ / cm 2 The exposure energy of the inventive example 2 needs 40mJ / cm 2 exposure energy), however, a satisfactory pattern can be formed after thermal transfer, exposure and water development.

Abstract

According to the present invention, in a thermosensitive transfer film F in which at least a fluorescent substance layer 3 and an adhesive agent layer 4 are deposited onto a base film 1, this adhesive agent layer 4 is produced by mixing at least a pigment corresponding to a color of the fluorescent substance layer 3, a thermosensitive agent and a photosensitizer. Also, a display device manufacturing method comprises the steps of forming patterning by exposure and development and using the adhesive agent layer 4 as a color filter layer after the fluorescent substance layer 3 and the adhesive layer 4 have been transferred onto the inner surface of the display panel from this thermosensitive transfer film F. Thus, in the thermosensitive transfer film in which layers are formed by the transfer process, work efficiency of the transfer process can be improved, and the sharp pattern can be formed.

Description

technical field [0001] The present invention relates to a thermosensitive transfer film for forming a phosphor layer in a display device such as a color cathode ray tube, and a method of manufacturing the display device. Background technique [0002] In recent years, as display devices including color cathode ray tubes have increased in size and their display screens have become flatter, demands for improvement in contrast and color purity of display devices have greatly increased from the viewpoint of quality. As a proposal capable of improving the contrast of a display device, a method of providing a color filter layer corresponding to a phosphor layer between a plate glass and a phosphor layer has been proposed (for example, Cited Patent Reference 1). [0003] Since the color filter layer is arranged between the phosphor layer of each color and the plate glass, although the transmittance of light is slightly lowered, the reflectance is lowered and thus the contrast ratio ...
