摘要： An illumination apparatus includes a main light source, a half mirror, and a diffusion plate. The main light source emits main light. The half mirror is spaced apart from the main light source. The half mirror reflects a first light travelling in a first direction among the main light source. The half mirror has a reflective surface reflecting the first light to travel in a second direction. The diffusion plate is disposed between the main light source and the half mirror not overlapping the reflective surface. The diffusion plate has a first horizontal surface and a second horizontal surface. The second horizontal surface is a rear surface of the first horizontal surface. The diffusion plate transmits a second light incident on the first horizontal surface among the main light. The diffusion plate scatters the second light from the second horizontal surface.

摘要： A display apparatus includes a display panel configured to display an image, a light guide member below the display panel, a light source adjacent to at least one surface of the light guide member, and an optical member between the light guide member and the display panel. The optical member includes a wavelength conversion layer configured to convert a wavelength band of incident light. A low refractive index layer between the wavelength conversion layer and the light guide member and including a plurality of pores, and an inorganic layer between the low refractive index layer and the wavelength conversion layer. A volume ratio occupied by the pores within the low refractive index layer increases as being closer to the light guide member.

摘要： There is provided a scan driver. The scan driver includes stages. An ith (i is a natural number) stage circuit includes an output unit, a controller configured to control the voltage of the second node in response to a kth (k is a natural number) clock signal supplied to a second input terminal, and an input unit configured to control the voltages of the first node and the second node in response to a carry signal of a previous stage that is supplied to a third input terminal and a carry signal of at least one next stage. The kth clock signal maintains a gate on voltage at a point of time at which a voltage of the jth clock signal is changed to a gate on voltage.
