Abstract

A display substrate includes; a base substrate, a deformation preventing layer disposed on a lower surface of the base substrate, wherein the deformation preventing layer applies a force to the base substrate to prevent the base substrate from bending, a gate line disposed on an upper surface of the base substrate, a data line disposed on the base substrate, and a pixel electrode disposed on the base substrate.

Description

technical field [0001] The invention relates to a display substrate and a manufacturing method of the display substrate. More particularly, exemplary embodiments of the present invention relate to a display substrate capable of preventing defects due to step differences and a method of manufacturing the display substrate. Background technique [0002] A liquid crystal display ("LCD") device displays images by applying a voltage to a liquid crystal layer interposed between two substrates to control light transmittance through the liquid crystal layer. Here, in order to apply a voltage, the LCD device generally includes electrodes formed on a display substrate and switching elements (eg, thin film transistors ("TFTs")) that apply data voltages to the electrodes. [0003] With the development of display technology, LCD devices are expected to have an increased display area, higher resolution, and faster response speed. Fulfilling the expectations for LCD devices mainly depend...
