Patent number: 6862070Abstract: An protective film and a resin layer are stacked on an insulation substrate on which a TFT is formed, and after a contact hole is formed in the resin layer, the protective film below the contact hole is etched and removed. A pixel display electrode is allowed to contact a drain electrode at the area of the contact hole; thus, a liquid crystal display is formed. A cut-out section, which communicates with the lower layer is formed in the drain electrode in the area of the contact hole. Upon forming a TFT section island-shape semiconductor layer so as to provide a TFT, a hole section island-shape semiconductor layer is also formed in the area of the contact hole. With this arrangement, it is possible to provide a manufacturing method of a liquid crystal display which can avoid the occurrence of a step discontinuity in the pixel display electrode and the subsequent disconnection in the pixel display electrode.Type: GrantFiled: December 5, 2003Date of Patent: March 1, 2005Assignee: Sharp Kabushiki KaishaInventors: Osamu Sugimoto, Hajime Imai

Patent number: 6750984Abstract: The present invention is directed to the provision of an image processing apparatus which enables the characteristic of an image region to be discriminated accurately, even in the presence of pixel displacements, noise, etc. Within masks for three colors, each mask consisting of m×n pixel including an object pixel, sub-region masks of u×v are set, and the sum of pixel densities is calculated by a sum calculation circuit. Based on the thus calculated sum, a parameter calculation circuit calculates a parameter based on which a multi-valued signal generation circuit generates a multi-valued signal. A characteristic signal represented by multi-valued data is generated by a characteristic signal generation circuit from the distribution of data within a region discriminating mask represented by the multi-valued signal, and a segmentation signal representing the result of region characteristic discrimination is output from a segmentation signal generation circuit.Type: GrantFiled: February 11, 2000Date of Patent: June 15, 2004Assignee: Sharp Kabushiki KaishaInventors: Toshihiro Kanata, Yasushi Adachi
