Embodiment approach

[0075] According to an exemplary embodiment, the optical sheet 240 including the transparent patterns 245 and the light scattering patterns 250 arranged alternately and repeatedly may be obtained without performing any patterning process. In addition, the light scattering layer 210 includes an adhesive 220 so that an additional adhesive layer may not be required.

[0076] Figure 9 to Figure 12 is a perspective view illustrating a method of manufacturing an optical sheet according to other exemplary embodiments.

[0077] refer to Figure 9 , the transparent layer 300 and the light scattering layer 310 may be alternately and repeatedly stacked.

[0078] The transparent layer 300 and the light-scattering layer 310 may respectively include and refer to image 3 The materials of transparent layer 100 and light scattering layer 110 are described as substantially the same or substantially similar materials. The process of arranging the transparent layer 300 and the light scatter...

Abstract

In a method of manufacturing an optical sheet, a stacked structure may be formed by alternatively and repeatedly stacking at least one transparent layer and at least one light scattering layer. A first cut face may be formed by partially cutting the stacked structure. A second cut face may be formed by partially cutting the stacked structure. The second cut face may be parallel to the first cut face.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0049193 filed with the Korean Intellectual Property Office on May 9, 2012, the entire contents of which are incorporated herein by reference. technical field [0003] Exemplary embodiments relate to a method of manufacturing an optical sheet having improved optical characteristics, an organic light emitting display device including the optical sheet having improved optical characteristics, and a method of manufacturing an organic light emitting display device including the optical sheet having improved optical characteristics. Background technique [0004] An organic light emitting display (OLED) device may display desired information such as images, letters, and / or characters using light generated by combining holes supplied from an anode and electrons supplied from a cathode within an organic layer thereof. The OLED device can secure a relati...
