Light-Emitting Device, Light-Emitting Apparatus, Electronic Device, and Lighting Device

A light-emitting device comprising:

• a first electrode;
• a second electrode;
• and
• a first layer,
• wherein the first layer comprises a region sandwiched between the first electrode and the second electrode,
• wherein the first layer comprises a light-emitting material, a first material, and a second material,
• wherein the first material comprises a first anthracene skeleton and a first substituent,
• wherein the first substituent is bonded to the first anthracene skeleton,
• wherein the first substituent comprises a heteroaromatic ring,
• wherein the second material comprises a second anthracene skeleton, a second substituent, and a third substituent,
• wherein the second substituent is bonded to the second anthracene skeleton,
• wherein the second substituent comprises an aromatic ring whose ring structure is composed of carbon,
• wherein the third substituent is bonded to the second anthracene skeleton,
• wherein the third substituent comprises an aromatic ring whose ring structure is composed of carbon, and
• wherein the third substituent has a different structure from the second substituent.
