PROBLEM TO BE SOLVED: To provide a backlight device and a liquid crystal display in which an optical film causing defects by irregularity and uneven optical efficiency is improved. SOLUTION: The backlight device of a liquid crystal display comprises: a frame; a first supporting portion disposed on the frame; a second support portion further disposed on the frame; a first constraining portion; a second constraining portion; and a film positioned on the frame by the first supporting portion and the second supporting portion passing through the first constraining portion and the second constraining portion, respectively. When the frame is disposed in a first position, the first supporting portion comes into partial contact with an inner wall of the first constraining portion for positioning the film. When the frame is disposed in a second position, the second supporting portion comes into partial contact with an inner wall of the second constraining portion for positioning the film. A liquid crystal display panel is also disclosed. COPYRIGHT: (C)2006,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a liquid crystal display (LCD) with improved motion image quality. SOLUTION: The LCD displays a frame during a frame time. A pixel of the LCD has a first switch and a second switch. At a first time point, the first switch is turned on by a video scan line, and a video data signal is transmitted to the pixel through a video data line, which makes the pixel have first luminance intensity. At a second time point, the second switch is turned on by a particular color signal scan line, and a particular color signal is transmitted to the pixel through a particular color signal data line, which makes the pixel have second luminance intensity smaller than the first luminance intensity. A time interval between the second time point and the first time point is smaller than the frame time and the after-image phenomenon is avoided. COPYRIGHT: (C)2006,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a multi-color EL display capable of alleviating attenuation of light having a specific emission color. SOLUTION: In this multi-color EL display provided with a pixel region installed on a substrate, and a plurality of sub-pixels installed in the pixel region, the sub-pixel has a multilayered deposition structure including a color light emitting unit comprising an electroluminescent material which emits light with a specific color, and the pixel region is provided with the sub-pixels having at least two or more kinds of multilayered deposition structure. Thereby, this multi-color EL display emits light with two or more different colors. The size and deposition of the sub-pixel are varied by changing the number of light emitting units in the sub-pixel and their region to compensate attenuation of the color of the sub-pixel.

PROBLEM TO BE SOLVED: To provide a liquid crystal display which hardly generates a tile-shaped pattern due to a photolithography process and has higher display performance than before. SOLUTION: In the center of a TFT-substrate side pixel electrode 116, a slit 116a parallel to a gate bus lines 111 is formed. On a counter-substrate side, a projection 124 is formed. This projection 124 comprises a projection 124a arranged along the left edge of the upper half part of the pixel electrode 116, a projection 124b which horizontally extends from the center of the projection 124a, a projection 124c which is arranged along the right edge of the lower half part of the pixel electrode 116, and a projection 124d which horizontally extends from the center of the projection 124c. Liquid crystal molecules 130a are aligned at nearly 45° to the projection 124 and the edges of the pixel electrode 116. COPYRIGHT: (C)2005,JPO&NCIPI
