A display substrate and a display device including the same are provided. The display substrate includes a first substrate which is divided into a display portion including pixel regions and a non-display portion including a region other than the display portion. Color filters are formed in the pixel regions of the substrate to respective thicknesses. At least one stepped pattern is formed on the non-display portion of the substrate and from the same material as used to form at least one of the color filters. The stepped patterns are formed at an area occupancy density of 20% or more of the non-display portion. A minimum distance is maintained between the stepped patterns and the pixel regions.

The present invention relates to a passive wavelength division multiplexing device for automatic wavelength locking and a system thereof including an optical multiplexer, an optical filter, an integrated optical receiver monitor, and a tunable optical transmitter. Through wavelength locking that adjusts a wavelength of an optical signal, which changes according to an external environment such as a temperature change, into a wavelength of an optical signal having the maximum optical intensity, communication quality may be maximized by securing a stable communication channel, a locking time and a communication channel setting time may be reduced, and more robust locking may be guaranteed.

There is provided a multilayer ceramic electronic component. The multilayer ceramic electronic component includes a ceramic main body including a dielectric layer, and first and second internal electrodes disposed to face each other within the ceramic main body and having the dielectric layer interposed therebetween. When an average roughness of center lines of the first and second internal electrodes is Ra, a maximum distance from a virtual line corresponding to Ra to a bottom of a pit (d) formed below the virtual line is 0.1 μm to 13 μm. The surface roughness of the internal electrode printed surface is improved to decrease the occurrence of electrical shorts.

A semiconductor device package includes a semiconductor chip and a plurality of inner leads, each having at least one slot formed along an upper surface of the inner lead. An adhesive layer is used to attach a bottom surface of the semiconductor chip to the upper surface of the inner lead. An encapsulant is allowed to flow in a package body mold, around the inner leads and through the slot. The slots prevent the production of turbulence along a side surface of the inner lead opposite to the flow direction, thereby avoiding problems associated with incomplete encapsulation such as the internal voids.
