Abstract
The present invention relates to a method for producing a liquid crystal panel. The method includes curing a first reactive mesogen layer with ultraviolet light at an illuminance within a range of 40 to 90 mW/cm. The liquid crystal panel includes a first transparent base material, a TFT layer and a first alignment film stacked in order on the first transparent base material, a second transparent base material, a color filter layer, an in-cell retardation layer, and a second alignment film stacked in order on the second transparent base material, a liquid crystal layer sandwiched between the first alignment film and the second alignment film, an out-cell retardation layer disposed on a side opposite to a color filter layer side of the second transparent base material, and a pair of linearly polarizing plates arranged so as to sandwich the first transparent base material and the out-cell retardation layer and having transmission axes orthogonal to each other. The in-cell retardation layer includes the first reactive mesogen layer and a second reactive mesogen layer. The first reactive mesogen layer and the second reactive mesogen layer have different material wavelength dispersibilities and have slow axes arranged orthogonal to each other.
