Problems solved by technology

In addition, certain parts of the curved surface of the lens pattern may not even be coated with polymer solution, which will cause molecular orientation defects of liquid crystals
[0013] Secondly, when the alignment polymer film is rubbed with an alignment cloth, a part of the structure, especially the convex part between adjacent concave lens patterns, may be damaged by the alignment cloth, resulting in molecular orientation defects of the liquid crystal

Embodiment Construction

[0031] The present invention will now be described in detail based on exemplary embodiments of the present invention, examples of which are shown in the accompanying drawings. Wherever possible, the same reference numbers are used to refer to the same or similar parts in all the drawings.

[0032] In the following description of the embodiments of the present invention, if the first structure is described as being formed (or disposed) on the second structure, the first structure and the second structure may be in contact with each other, or there may be additional layers inserted in Between the first structure and the second structure. However, if the first structure is described as being directly formed (or provided) on the second structure, it is defined as a case where the first structure and the second structure are in direct contact with each other.

[0033] Below, will refer to Figure 1 to Figure 3 The conversion lens according to the first embodiment of the present invent...

Abstract

Disclosed are a switching lens and a method for manufacturing the same. The switching lens having liquid crystals of highly uniform orientation can be obtained by minimizing the thickness deviation of an alignment film formed on the whole curvature surface of a lenticular pattern. The switching lens of the present invention comprises a resin layer having a lenticular pattern and an alignment film on the resin layer. The alignment film covers the whole curvature surface of the lenticular pattern and has the maximum thickness equal to or less than 0.01 times the maximum radius of curvature of the lenticular pattern.

Description

Technical field [0001] The present invention relates to a conversion lens used in a display device and a manufacturing method thereof, and more specifically, to a conversion lens having a highly uniformly oriented liquid crystal and a manufacturing method thereof. The thickness deviation of the alignment film formed on the entire curved surface of the lens pattern is obtained. Background technique [0002] The principle of binocular stereo vision enlightens the three-dimensional display of three-dimensional images. The binocular parallax caused by the distance between the two eyes by approximately 65 mm is one of the most important factors of stereocognosy. [0003] When different two-dimensional images input through the left and right eyes are input into the brain, the brain combines these images to reproduce the depth and realism of the original three-dimensional image. The technique of using binocular vision to generate three-dimensional images is called stereography. A 3D di...
