Abstract

The invention discloses a LCD device and manufacturing method which can improve the aperture opening ratio. The LCD device includes a baseplate provided with a resistor region, a pixel region and a storage capacitance region; a resistor arranged in the resistor region of the baseplate, which is provided with a first transparent conductive layer, a pictorial first conductive layer, an dielectric layer, a pictorial semi-conductive layer, a pictorial second conductive layer and a pictorial second transparent conductive layer superimposed in order; a storage capacitor arranged in the storage capacitance region of the baseplate; and a pixel electrode arranged in the pixel region of the baseplate. The invention takes a storage capacitor with two pictorial transparent conductive layers as the electrode for light transmittance, to increase the light transmittance area of the display device and improve the aperture opening ratio.

Description

technical field [0001] The present invention relates to a liquid crystal display device and a manufacturing method thereof; in particular, to a liquid crystal display device capable of increasing the aperture ratio and a manufacturing method thereof. Background technique [0002] Existing thin film transistor (TFT) liquid crystal display devices are composed of upper and lower substrates, and various components are included in the middle, such as transistors, storage capacitors, pixel electrodes, scanning lines, data lines and so on. When designing a liquid crystal display device, usually the transistor structure is first determined according to the TFT manufacturing process, and then the storage capacitor structure is determined. The storage capacitor has two electrodes, and generally at least one electrode is an opaque electrode, so the storage capacitor will reduce the aperture ratio of the liquid crystal display device. It is generally known that the aperture ratio is d...
