    Abstract: A composite sheet includes a first sheet and a second sheet. The first sheet includes a first substrate and a first optical pattern layer disposed on an upper surface of the first substrate. The second sheet is disposed on the first sheet. The second sheeting includes a second substrate and a second optical pattern layer disposed on an upper surface of the second substrate. An extending direction of the first optical pattern layer intersects an extending direction of the second optical pattern layer such that an intersection angle of the extending direction of the first optical pattern layer and the extending direction of the second optical pattern layer is in a range of 40° to 70°.

    Abstract: An optical member including a light guide plate including a surface disposed on a plane defined by a first direction and a second direction crossing the first direction, a low refractive index pattern disposed on the surface of the light guide plate and including an opening for exposing the surface of the light guide plate, a wavelength conversion layer disposed on the low refractive index pattern, and a passivation layer disposed on the wavelength conversion layer and covering a side surface of the wavelength conversion layer and a side surface of the low refractive index pattern at least one side portion. The low refractive index pattern has a lower index of refraction than the light guide plate, and a ratio of an area occupied by the low refractive index pattern to an area of the surface of the light guide plate decreases in the first direction.
