摘要： A solid-state imaging device is composed of a P-type semiconductor layer, an interlayer insulation film, a multilayer interference filter and condenser lenses which have been successively laminated on an N-type semiconductor layer. A photodiode, in which N-type impurities have been ion-implanted, is formed per pixel in the P-type semiconductor layer on the interlayer insulation film side. The multilayer interference filter has a composition including λ/4 multilayer films and a plurality of spacer layers sandwiched therebetween. The λ/4 multilayer films are composed of alternately laminated monotitanium dioxide layers and monosilicon dioxide layers that have the same optical thickness. The spacer layers have optical thicknesses corresponding to colors of light they are to transmit. A spacer layer is not included in a green region. Instead, two monotitanium dioxide layers, each of which constitutes a λ/4 multilayer film, are adjoined to make a monotitanium dioxide layer with an optical thickness of λ/2.

摘要： A display panel apparatus includes pixels. Each pixel includes an organic luminescent layer between an upper electrode and a lower electrode and is configured to emit a red, a green, or a blue light. A glass substrate is above the upper electrode. A lens sheet is between the pixels and the glass substrate and includes lenses and a base. Each lens corresponds to a pixel and protrudes from the base. Partitions are between the glass substrate and the lens sheet for partitioning the lenses. The partitions have a first height that is greater than a second height of the lenses. The base includes trenches between the lenses. The trenches are recessed in a direction opposite the lenses. The partitions are in the trenches. Each partition has a cross-section that includes an upper side that has a different length than a bottom side and lateral sides that are tilted.
