System for display images

Abstract

A system for displaying images including a display panel is provided. The display panel has a display area and a peripheral area. The display panel includes a metal layer disposed on a first substrate. A patterned planarization layer is disposed on the metal layer, having at least one opening corresponding to the peripheral area, wherein a portion of the metal layer is exposed through the opening. A second substrate is disposed opposite to the first substrate. A seal is disposed at the peripheral area and between the first and the second substrates, wherein the seal covers the metal layer through the opening of the patterned planarization layer.

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This Application claims priority of Taiwan Patent Application No. 100122869, filed on Jun. 29, 2011, the entirety of which is incorporated by reference herein.BACKGROUND[0002]1. Field of the Invention[0003]The disclosure relates to a system for displaying images including a display panel, and more particularly to a display panel with a patterned planarization layer.[0004]2. Description of the Related Art[0005]Generally, a color filter (CF) substrate and an array substrate are bonded together by a seal. Then, a space between the two substrates is filled with a liquid crystal material to form a liquid crystal display panel.[0006]In conventional liquid crystal display panels, after a plurality of thin-film transistors (TFTs) and a plurality of scan lines and data lines are formed on the array substrate, a planarization layer is blanketly formed over the array substrate to cover the TFTs, the scan lines, and the data lines.

AI Technical Summary

Benefits of technology

The invention provides a system for displaying images using a display panel with a patterned planarization layer that improves the bonding force between two substrates. This prevents peeling issues during the manufacturing process and increases the yield of liquid crystal display panels.

Problems solved by technology

The adhesion between a material of the planarization layer and a metal material used for the scan lines and the data lines and the adhesion between a material of the planarization layer and an inorganic material used for the TFTs, such as silicon oxide or silicon nitride are poor.

Thus, peeling easily occurs between the planarization layer and the metal lines of the scan lines and the data lines, and between the planarization layer and the inorganic material of the TFTs.

If so, then, there is poor bonding between the CF substrate and the array substrate, which may lead to the separation of the CF substrate and the array substrate.

Therefore, the yield of the conventional liquid crystal display panels is poor.
