  • Liquid crystal display comprising a semiconductor layer integrally formed and including a crossover portion, a TFT portion, and a connection portion and manufacturing method for the same
    Patent number: 7952670
    Abstract: According to an aspect of the present invention, there is provided a liquid crystal display that includes a gate electrode and line formed on a transparent insulating substrate, a gate insulating film covering the gate electrode and line, a semiconductor layer formed on the gate insulating film, a source electrode, a source line, and a drain electrode formed on the semiconductor layer, and a pixel electrode connected to the drain electrode. The semiconductor layer is integrally formed of three portions which are a crossover portion of the source line and the drain line, a TFT portion, and a connecting portion connecting the crossover portion to the TFT portion. A part of the crossover portion on the connecting portion side and the whole connecting portion are covered by the source electrode and the source line.

  • Substrate with light-shielding film, color filter substrate, method of manufacture of both, and display device having substrate with light-shielding film
    Publication number: 20070026324
    Abstract: A substrate with a light-shielding film according to one mode of the invention is obtained in a method of manufacture of a substrate with a light-shielding film having a light-shielding film pattern formed on a substrate, by depositing in order a first film having chromium oxide and a second film having chromium on a substrate, to form a multilayer film; forming a resist pattern on the multilayer film; performing etching of the multilayer film, using an etching liquid comprising ceric ammonium nitrate to which nitric acid is added at a concentration of at least 2.5 mol/liter, to form a light-shielding film pattern; and removing the resist pattern.
