Abstract: There is provided a cutting method of a wafer for cutting the wafer that includes a circular recess part and an annular projection part. The cutting method of a wafer includes a tape sticking step of sticking an adhesive tape along the recess part and the projection part, a holding step of sucking the adhesive tape stuck to the recess part by a holding surface of a chuck table having the holding surface with a smaller diameter than the recess part to hold the wafer by the chuck table with the interposition of the adhesive tape, and a cutting step of separating the recess part and the projection part by making a cutting blade that rotates cut into the wafer and rotating the chuck table in the state in which the projection part is not fixed.

Abstract: There is provided a processing method of a wafer for processing the wafer that includes, on a front surface side, a device region in which a device is formed in each of plural regions marked out by plural planned dividing lines and includes a recess part on the back surface side and includes an annular reinforcing part at a peripheral part. The processing method of a wafer includes a holding step of holding the bottom surface of the recess part, a cutting step of cutting the wafer along the planned dividing lines by a cutting blade to divide the device region into plural device chips and form grooves on the front surface side of the reinforcing part, and a dividing step of dividing the reinforcing part along the planned dividing lines with the grooves being the points of origin by giving an external force to the reinforcing part.

Abstract: Provided is a color display element which employs a conventional system of monochrome electronic paper without degrading the degree of brightness and with ease and lower costs. Also provided is a method of producing a color display element including a pair of opposing substrates having electrodes, charged display bodies of white color and black color which are enclosed between the opposing substrates, and a color filter which is disposed on one of the opposing substrates, the method including forming a color filter disposed on a viewing side by forming, first, colored regions of at least three colors of blue, green, and red by an inkjet method on a transparent support substrate, and forming remaining regions other than the colored regions so as to be colorless or transparent.

Abstract: Provided are a lenticular lens sheet which can be used in a stereoscopic display, a rear projection display, a projection screen, and the like, and means for manufacturing the lenticular lens sheet at low cost without using any mold. The lenticular lens sheet includes at least a transparent support substrate; a plurality of lenticular lenses; and a partition between adjacent ones of the plurality of lenticular lenses, and the lenticular lens sheet is obtained by applying a transparent resin composition ink by an inkjet method to an area partitioned by the partition and subsequently curing the transparent resin composition ink with ultraviolet rays.

Abstract: Provided are a color display device capable of colorized display in a reflection type display device which is adopted to electronic paper and the like without degrading the degree of brightness and with high efficiency, and also with ease and lower costs, and a method of producing the same.
