Problems solved by technology

However, the Mo-including material and the transparent conductive material have poor adhesiveness with an organic insulating layer.
Therefore, the organic insulating layer interposed between the data lines and the pixel electrodes may easily come off therefrom to induce defects such as an open data line and to produce particles.
As a result, productivity is degraded.

Embodiment Construction

[0040] Preferred embodiments of the present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. The present invention may, however, be embodied in different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0041] In the drawings, the thickness of layers, films, and regions are exaggerated for clarity. Like numerals refer to like elements throughout. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being “on” another element, it can be directly on the other element or intervening elements may also be present.

Abstract

The present invention provides a thin film transistor array panel comprising: an insulating substrate; a first signal line formed on the insulating substrate and extending in a first direction; a second signal line formed on the insulating substrate, extending in a second direction, and intersecting the first signal line; a thin film transistor connected to the first and second signal lines; a passivation layer formed on the second signal line and having a contact hole exposing a portion of the second signal line; and a pixel electrode formed on the passivation layer and connected to the thin film transistor through the contact hole, wherein the passivation layer is formed by coating an organic solution that includes an organic insulating material and a solvent including at least one of PGMEP, EEP, and nBA.

Description

BACKGROUND OF THE INVENTION [0001] (a) Field of the Invention [0002] The present invention relates to a thin film transistor array panel. [0003] (b) Description of the Related Art [0004] An LCD is one of the most popular flat panel displays. Generally, a liquid crystal display has two substrates with electrodes, and a liquid crystal layer sandwiched between the two substrates. Voltages are applied to the electrodes so that the liquid crystal molecules in the liquid crystal layer are re-oriented to thereby control light transmission. [0005] A basic LCD has two substrates respectively having electrodes for producing an electric field. One of the two substrates has a plurality of pixel electrodes arranged in a matrix shape, and the other has a common electrode covering the entire display area of the substrate. [0006] The liquid crystal display has a plurality of pixels with pixel electrodes. The pixels are driven by way of signals applied through the wiring lines. The wiring lines incl...
