ABSTRACT:
A reflection type liquid crystal display panel is arranged such that between an active matrix substrate and an opposing substrate there are provided thin film transistors, interlayer insulating film, pixel electrodes, light reflecting films, orientation film, phase transition type guest/host liquid crystal, orientation film, opposing electrode, and color filter in this order. The pixel electrodes are disposed on the active matrix substrate in the form of a matrix with the interlayer insulating film interposed therebetween and also are respectively connected to the thin film transistors. The light reflecting films are each formed by the upper surface of the pixel electrode per se being made into a porous layer. The porous layer formed as the light reflecting film can make the light scattering large in amount and can also reflect the light in a desired direction by changing its pore size or depth. Therefore, the liquid crystal display panel can be applied as liquid crystal display panels for use in a wide range of electronic devices. That is, a liquid crystal display panel high in luminance can be provided by making the light reflecting film into a porous layer and making the light scattering large in amount.
