Recently, as the display rapidly develops, a lot of research and development related to display technologies are being carried out. In particular, organic light emitting diode (OLED) display devices have complicated optical structures on the nanoscale and different luminescent properties depending on the polarization of light. To analyze this complicated OLED displays, the methods for Electromagnetic (EM) field analysis such as the finite difference domain (FDTD), the finite element method (FEM) and the rigorous coupled-wave analysis (RCWA) are generally used. In this study, we used Fourier modal method (FMM)  based on RCWA to calculate the EM field. However, to calculate the EM field of a large-area display using the FMM, it is necessary to use a high-resource computer or a special methodology for parallel computation. Therefore, we propose a method for parallel process of FMM that can perform calculations on general level calculation systems such as a personal computer (PC).
