Abstract:
An active-matrix addressing LCD device that suppresses effectively the off leakage current induced by the charge-up of the spacers placed over the TFTs. The device comprises (a) a first substrate having switching elements; (b) a second substrate coupled with the first substrate in such a way as to form a gap with spacers between the first and second substrates; the spacers being distributed in the gap; (c) a liquid crystal confined in the gap; and (d) protrusions formed in overlapping areas with the switching elements; each of the protrusions being protruded in a direction that narrows the gap. The spacers distributed in the gap are likely to be shifted away from the overlapping areas due to the protrusions.
Abstract:
In a transflective type LCD provided with a transparent region and a reflection region in each pixel, when an irregular film 11 is formed on an active matrix substrate 12 to form irregularities of a reflection electrode film 6, the irregular film 11 is specifically formed to almost the same film thickness in both the transparent region and the reflection region to provide substantially the same inter-substrate gap in these two regions so that they may have almost the same V-T characteristics and also the reflection electrode film 6 made of Al/Mo is formed so as to overlap with a transmission electrode film 5 made of ITO all around an outer periphery of the transmission electrode film 5 by a width of at least 2 nullm, thus suppressing electric erosion from occurring between the ITO and Al substances at the edge of the transmission electrode film 5.
Abstract:
In a semi-transmission type liquid crystal display and a method for fabricating the same, a reflective electrode such as aluminum layer and a transparent electrode such as ITO film are used to form a pixel electrode that is provided on an organic film having an uneven surface. In order to effectively restrict the battery effect between a reflective electrode and a transparent electrode, a surface of the organic film is put in a plasma-processing and then is washed by a washing liquid. Thereafter, the transparent electrode is formed and then the reflective electrode such as a double layer electrode of the aluminum layer and the molybdenum layer are formed.
Abstract:
The present invention provides a liquid crystal display apparatus of a lateral direction electric field drive type comprising an array substrate including a plurality of TFTs each having a gate electrode, a gate insulation film, a semiconductor layer, and a source electrode/drain electrode formed on a transparent substrate and an opposing substrate arrange so as to oppose to the array substrate, wherein the semiconductor layer has a width in the gate length direction identical to the gate length.
Abstract:
An active matrix substrate plate having superior properties is manufactured at high yield using four photolithographic fabrication steps. In step 1, the scanning line and the gate electrode extending from the scanning line are formed in the glass plate. In step 2, the gate insulation layer and the semiconductor layer comprised by amorphous silicon layer and nnull amorphous silicon layer is laminated to provide the semiconductor layer for the TFT section. In step 3, the transparent conductive layer and the metallic layer are laminated, and the signal line, the drain electrode extending from the signal line, the pixel electrode and the source electrode extending from the pixel electrode are formed, and the nnull amorphous silicon layer of the channel gap is removed by etching. In step 4, the protective insulation layer is formed, and the protective insulation layer and the metal layer above the pixel electrode are removed by etching.
