The method includes curing a first reactive mesogen layer with ultraviolet light at an illuminance within a range of 40 to 90 mW/cm2. 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.

Abstract: A display apparatus according to one embodiment comprises pixels each comprising a liquid crystal display element (LC element) and an organic EL display element (EL element). The EL element comprises an anode and a cathode electrically separated from each electrode of the LC element. Each pixel comprises a first transistor which changes the magnitude of a current flowing through the EL element based on the potential of a first bus line; a second transistor which electrically separates the first bus line and the LC element; and a third transistor which electrically connects the first and second transistor with the first bus line. A method for driving a display device according to one embodiment reduces the potential difference between the pixel electrode and the counter electrode before turning off the second transistor during switching from display by the LC element to display by the EL element.
