Patent number: 9310605Abstract: A display apparatus includes a first substrate and a second substrate. The first substrate includes a light shielding layer including a first opening which transmits a light. The second substrate includes a shutter including a second opening which corresponds to the first opening, and a first flexible electrode part which is connected to one end of the shutter and transmits or blocks the light by moving the shutter. The first flexible electrode part includes a first flexible electrode, a second flexible electrode, and an insulation pattern. The insulation pattern insulates the first flexible electrode and the second flexible electrode from each other, and exposes upper and lower surfaces of the first flexible electrode and the second flexible electrode which are parallel to the second substrate, by covering portions of the first flexible electrode and the second flexible electrode.Type: GrantFiled: August 30, 2013Date of Patent: April 12, 2016Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Dae Hyun Kim, Jae Byung Park, Chun-Ho Song, Donchan Cho, Sungsik Yun, Yu-Kwan Kim

Patent number: 9200778Abstract: 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<90+sin?1(1/n), where A1 an obtuse angle between a main axis and a tangent line of the curved centermost surface, and A2 is an acute angle between a straight line linking the center of the base to the point of the curved centermost surface and the main axis.Type: GrantFiled: October 21, 2013Date of Patent: December 1, 2015Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Ju-Young Yoon, Gi-Cherl Kim, Jong-Seo Lee, Chun-Ho Song, Se-Ki Park, Sang-Gil Lee, Seock-Hwan Kang
