Abstract: A display device includes: a lower panel through which incident light passes and including a substrate on which a thin film transistor is disposed; a color conversion display panel from which converted light is emitted to display an image and overlapping the lower panel; and a polarization film between the lower panel and the color conversion display panel. The color conversion display panel includes a substrate on which are disposed: a first color conversion layer including first semiconductor nanocrystals which convert the incident light to the converted light; a second color conversion layer including second semiconductor nanocrystals which convert the incident light to the converted light; and a transmission layer through which unconverted incident light passes. The substrate of the lower panel or the color conversion display panel includes a flexible substrate including a polymer.

Abstract: A lens has a refractive index of n, and includes a base, a first curved circumferential surface extending from the base, a curved center-edge surface extending from the first curved circumferential surface, and a curved centermost surface extending from the curved center-edge surface. The base includes a groove for receiving a light emitting chip. A distance from a center of the base to a point of the curved center-edge surface is shorter than the radius of curvature for the point of the curved center-edge surface. The curved centermost surface has a concave shape with respect to the base. The lens satisfies A1+A2

Abstract translation: 透镜具有n的折射率，并且包括基部，从基部延伸的第一弯曲圆周表面，从第一弯曲圆周表面延伸的弯曲的中心边缘表面和从弯曲的中心边缘延伸的弯曲的中心表面 表面。 基座包括用于接收发光芯片的凹槽。 从基部的中心到弯曲的中心边缘表面的点的距离比弯曲的中心边缘表面的点的曲率半径短。 弯曲的中心表面相对于基部具有凹形。 透镜满足A1 + A2 <90 + sin-1（1 / n），其中A1是主轴与弯曲中心表面的切线之间的钝角，A2是连接中心的直线之间的锐角 的基部至弯曲的最中心表面和主轴线的点。
