Benefits of technology

The solution improves the optical efficiency of the LCD by eliminating the gap causing color shift, enhancing color saturation and contrast, and reducing power consumption by optimizing the covering layer thickness and exposure processes.

Problems solved by technology

Mixed RGBW LCDs, however, suffer from many drawbacks.

Embodiment Construction

[0025]The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the present invention and should not be taken in a limiting sense. The scope of the present invention is best determined by reference to the appended claims.

[0026]In this specification, expressions such as “overlying the substrate”, “above the layer”, or “on the film” simply denote a relative positional relationship with respect to the surface of the base layer, regardless of the existence of intermediate layers. Accordingly, these expressions may indicate not only the direct contact of layers, but also, a non-contact state of one or more laminated layers.

[0027]FIG. 2 shows a cross section of a single gap transflective liquid crystal display according with a preferred embodiment of the present invention. Referring to FIG. 2, a first substrate 200, which the materials may comprise transparent material such a...

Abstract

A method for fabricating a display is disclosed. A first substrate comprising a plurality of pixels is provided, each pixel comprises a plurality of sub pixels. A second substrate substantially opposite to the first substrate is provided, wherein the second substrate is divided into a plurality of regions corresponding to the sub-pixels, and at least three of the regions are color regions and at least one of the regions is a fourth region. A photoresist pattern layer is formed on the second substrate, such that the photoresist pattern layer corresponding to the at least three color regions are color photoresist pattern layers and the photoresist pattern layer corresponding to the at least one fourth region is a fourth photoresist pattern layer. A first covering layer is formed on the photoresist layer. A liquid crystal layer is interposed between the first substrate and the second substrate.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of pending U.S. patent application Ser. No. 11 / 554,657, filed Oct. 31, 2006 and entitled “TRANSFLECTIVE LIQUID CRYSTAL DISPLAYS AND METHODS FOR FABRICATING THE SAME”, which is hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a display and methods for fabricating the same, and more particularly, to a liquid crystal display and methods for fabricating the same.[0004]2. Description of the Related Art[0005]Liquid crystal displays (LCD) are commonly used for flat panel displays. Owing to dielectric anisotropy and conductive anisotropy of liquid crystal molecules, molecular orientation of liquid crystals can be shifted under an external electronic field, such that various optical effects are produced. The panel structure of an LCD typically comprises two laminated substrates separated by a gap and liquid crystal injected therebetw...
