A method for preparing a lithographic printing plate is provided which comprises the steps of providing a lithographic printing plate precursor comprising (i) a support having a hydrophilic surface or which is provided with a hydrophilic layer, (ii) on said support, a coating comprising an image recording layer, said layer comprising hydrophobic thermoplastic polymer particles, having an average particle size between 40 nm and 63 nm and a hydrophilic binder, said coating further comprising a pigment, present in said image recording layer or in an additional layer of said coating, image-wise exposing said coating, thereby inducing coalescence of the thermoplastic polymer particles at the exposed areas of the image recording layer, developing the precursor by applying a gum solution to the coating, thereby removing the non-exposed areas of the image recording layer from the support, and optionally, baking the developed precursor, wherein the hydrophobic thermoplastic polymer particles have an average particle size between 40 nm and 63 nm, wherein the amount of the hydrophobic thermoplastic polymer particles is more than 70 % and less than 85 % by weight, relative to the image recording layer, and wherein said pigment has a hydrophilic surface and provides a visible image after image-wise exposing and developing with the gum solution. The lithographic printing plate precursor, used in the above method, has an improved sensitivity, and the obtained lithographic printing plates exhibit an excellent clean-out, no toning and a high printing run length.

A liquid crystal panel or the present invention comprising a liquid crystal cell, a first polarizer and a second polarizer provided on both sides of the liquid crystal cell, a first optical compensation layer provided between the liquid crystal cell and the first polarizer, and a second optical compensation layer provided between the liquid crystal cell and the second polarizer, wherein a wavelength dispersion of the liquid crystal cell satisfies Re40(450)>Re40(550)>Re40(650), an index ellipsoid of the first optical compensation layer satisfies a relationship of nx>nz>ny, and a wavelength dispersion of the second optical compensation layer satisfies Re40(450)≧Re40(550)≧Re40(650).
