Abstract: A lamination includes a sheet substrate and a display element layer. The sheet substrate includes a plurality of product regions cut out into a plurality of products and a blank region surrounding the product regions. The display element layer is formed on each of a plurality of display areas placed on each of the plurality of product regions for displaying an image. The sheet substrate adheres to a top of a substrate. The substrate has light transmissivity. A protective film is adhered to the lamination so as to cover the display areas. A divider line is formed in a blank region that surrounds the product regions by removing a portion of the lamination. The substrate is removed from the sheet substrate by irradiating the sheet substrate with a laser beam.

Abstract: The invention allows stable fabrication of a TFT circuit board used in a display device and having thereon an oxide semiconductor TFT. A TFT circuit board includes a TFT that includes an oxide semiconductor. The TFT has a gate insulating film formed on part of the oxide semiconductor and a gate electrode formed on the gate insulating film. A portion of the oxide semiconductor that is covered with the gate electrode 104 and a portion of the oxide semiconductor that is not covered with the gate electrode are both covered with a first interlayer insulating film. The first interlayer insulating film is covered with a first film 106, and the first film is covered with a first AlO film.

Abstract: A display device includes a side light type backlight for white color display by single color LEDs, an LED set is placed in a concave portion of a light guide plate, in which a first color LED is located in the center and a second or third color LED is located on the side of the first color LED. An incident slit with an arc shaped convex portion is formed facing the first color LED, and a saw tooth slit with a right-angled triangular concave portion is formed facing the second or third color LED. This allows directing the distribution axes of the lights from the second and third color LEDs to the center side, and adjusting orientation angles to allow effective mixing of the three color lights, in order to increase the white color area and effective display area.

Abstract translation: 显示装置包括通过单色LED进行白色显示的侧光型背光源，LED组置于其中第一颜色LED位于中央的导光板的凹部中，第二或第三颜色 LED位于第一色LED的一侧。 形成有与圆形凸部相对的入射狭缝，面向第一颜色LED，并且形成有与第二或第三颜色LED相对的具有直角三角形凹部的锯齿狭缝。 这允许将来自第二和第三颜色LED的光的分布轴指向中心侧，并且调整取向角以允许三色光的有效混合，以便增加白色区域和有效显示区域。
