Benefits of technology

[0014] The present invention provides a substrate for a display apparatus having improved image display quality.
[0018] The present invention also provides a color filter substrate capable of improving a viewing angle and an image display quality.
[0036] Therefore, the display apparatus includes a liquid crystal layer having a vertical alignment (VA) mode and the multi-domain so that the image display quality of the display apparatus is improved. The liquid crystal layer having the VA mode may be inclined by a predetermined pretilt angle. In addition, the display apparatus may be manufactured without a rubbing process. In particular, the liquid crystal layer includes the multi-domain so that the viewing angle of the LCD apparatus is improved. Furthermore, a manufacturing process of the display apparatus is simplified so that a manufacturing cost of the display apparatus is decreased.

Problems solved by technology

In a conventional LCD apparatus, the range of the viewpoint angle is restricted by image display quality deterioration.
However, when the transmissive-reflective LCD apparatus is manufactured without the rubbing process, a portion of the liquid crystal layer corresponding to a central portion of the transmission region may be misaligned so that the image display quality of the LCD apparatus is lowered.
When the transmissive-reflective LCD apparatus is manufactured through the rubbing process, manufacturing cost of transmissive-reflective LCD apparatus is increased.
In addition, the LCD apparatus may be non-uniformly rubbed so that the image display quality of the LCD apparatus is deteriorated.

Abstract

A substrate for a display apparatus includes a plate, a switching element, an insulating layer, and a partition wall. The plate has a reflection region on which a light that is provided from an exterior to the substrate is reflected and a transmission region through which a light generated from a backlight assembly passes. The switching element is on the plate. The insulating layer is on the plate having the switching element. The transmission region of the insulating layer is recessed when compared to the reflection region of the insulating layer. The insulating layer has a contact hole through which a first electrode of the switching element is partially exposed. The partition wall divides the transmission region into a plurality of transmission portions. Advantageously, an image display quality of the display apparatus is improved, and manufacturing cost is decreased.

Description

CROSS-REFERENCE OF RELATED APPLICATIONS [0001] The present application claims priority from Korean Patent Application No. 2004-00701, filed on Jan. 6, 2004 and Korean Patent Application No. 2004-13337, filed on Feb. 27, 2004, the disclosures of which are hereby incorporated herein by reference in their entireties. BACKGROUND [0002] 1. Field of the Invention [0003] The present invention relates to a substrate for a display apparatus, and more particularly, the present invention relates to a substrate for a display apparatus having improved image display quality, including but not limited to an improved viewing angle. [0004] 2. Description of the Related Art [0005] In an LCD apparatus that is one of flat panel display (FPD) apparatuses, generally, liquid crystal arrangement varies in response to an electric field applied to the liquid crystal, and thus a light transmittance of the liquid crystal may be changed to display an image. [0006] The LCD apparatus displays the image using the ...
