Abstract: Disclosed is a manufacturing method of a liquid crystal display device which is a manufacturing method of a liquid crystal display device including a liquid crystal alignment film to which an alignment regulating force is imparted by a photo-alignment treatment, including: a film forming step of forming a film containing a polymer whose main chain is cleaved by irradiation with light; a photo-alignment step of imparting an alignment regulating force to the film formed in the film forming step by irradiation of the film with light in an atmosphere of a temperature lower than 100° C.; and a removing step of removing a low-molecular weight component generated by cleaving the main chain of the polymer through the light irradiation after the light irradiation. Also disclosed is a liquid crystal display device manufactured by the manufacturing method.

Abstract: The present invention is intended to control the color temperature of white exhibited by a liquid crystal display device. White is produced when light waves emitted through pixels associated with three colors of red, green, and blue have maximum intensities. The amounts of light emitted through the respective pixels are controlled by differentiating the shapes of the pixel electrodes disposed at the respective pixels from one another. Thus, the color temperature of white is controlled. Otherwise, the shapes of interceptive films disposed at the respective pixels are differentiated from one another in order to control light waves emitted through the respective pixels. Thus, the color temperature of white is controlled. The interceptive film may be shaped like the pixel electrode. Otherwise, the interceptive film may be realized with an interceptive pattern other than that of the pixel electrode or one of openings bored in a black matrix.

Abstract: A manufacturing method of a touch panel includes the steps of providing a substrate, forming a first conductive film on the substrate, forming a first mask on the first conductive film, etching the first conductive film to form electrode portions and lower intersect portions of the touch panel, forming an insulating film made of a negative resist on the first conductive film, and forming a contact hole above the electrode portion by removing the insulating film. The steps further include forming a second conductive film on the insulating film, forming a second mask on the second conductive film, etching the second conductive film to form an upper intersect portion connected between two adjacent electrode portions via the contact hole and intersecting with the lower intersect portion, and forming protective film on the second conductive film.

Abstract: A touch panel includes a plurality of first electrodes, a plurality of second electrodes, and a plurality of wirings. Each of the plurality of first electrodes has a first portion formed on a layer different from that on which the second electrodes are formed and intersecting the second electrodes, and a second portion formed on the same layer as that on which the second electrodes are formed, but separated from the second electrode. The second electrode and the second portion of the first electrode are formed on a layer different than the layer where the wiring is formed. The first portion of the first electrode is connected to the second portion through a contact portion formed in an insulating film made of a negative resist between the first portion and the second electrode.
