Title:
DISPLAY METHOD AND DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2015161737
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a display device having a high optical performance, with small size, being thin.SOLUTION: A display device includes a space phase modulation element 30 for forming a display optical flux 2, a transparent substrate 40 in which the display optical flux 2 is repeatedly reflected on inner surfaces for propagation, a branch part 40c, each time the display optical flux 2 is internally reflected, makes a part of the display optical flux 2 ejected outside the transparent substrate 40, and an optical flux guiding-in optical system 70 which contains a beam splitter 73 that guides an illumination optical flux 1 to the space phase modulation element 30 so that the display optical flux 2 formed with the space phase modulation element 30 is guided to the transparent substrate 40. The space phase modulation element 30 forms the display optical flux 2 in a holographic manner by diffraction of the illumination optical flux 1.
